Mother-to-child transmission (MTCT) of the hepatitis B virus (HBV) is a serious public health challenge. Estimating HBV MTCT incidence by region under different prophylaxis regimens is critical to understanding the regional disease burden and prioritizing interventions. This study aimed to calculate HBV MTCT incidence under different prophylaxis regimens globally and regionally and identify the HBV DNA threshold for maternal peripartum antiviral prophylaxis.This review was registered in advance in PROSPERO (CRD 42019120567). We searched PubMed, Embase, China National Knowledge Infrastructure, ClinicalTrials.gov, and Cochrane Library databases for studies on MTCT in pregnant women with chronic HBV infection from their inception until June 13, 2022. MTCT was defined as hepatitis B surface antigen (HBsAg) or HBV DNA seropositivity in infants aged 6-12 months. We calculated the pooled HBV MTCT incidence using the DerSimonian-Laird random-effects model.Among 300 studies, 3402 of 63 293 infants had HBV due to MTCT. Without prophylaxis regimens, the pooled HBV MTCT incidence was 31.3%, ranging from 0.0% (95% confidence interval [CI] 0.0%-6.0%; European Region) to 46.1% (95% CI 29.7%-63.0%; Western Pacific Region). Following the introduction of the hepatitis B vaccine, the HBV MTCT incidence decreased from 82.9% to 15.9% in HBeAg-positive women and from 10.3% to 2.3% in HBeAg-negative women. Maternal peripartum antiviral treatment alongside infant immunoprophylaxis further decreased MTCT incidence to 0.3% (95% CI 0.1%-0.5%). Despite infant immunoprophylaxis, the incidences of MTCT at maternal HBV DNA levels of2.30, 2.00-3.29, 3.00-4.29, 4.00-5.29, 5.00-6.29, 6.00-7.29 and ≥7.00 logHBV MTCT incidence varies across regions. The Western Pacific Region bears the heaviest burden. Peripartum antiviral prophylaxis plus infant immunoprophylaxis is promising for interrupting HBV MTCT. Regarding the HBV DNA threshold for peripartum antiviral prophylaxis, maternal HBV DNA of 4.00 log

To explore the current state of research on off-label drug use in children and identify the existing research gaps in this topic. Six literature databases were searched to identify studies focusing exclusively on off-label drug use in children (aged 18 years) published in Chinese or English between 2016 and 2021. We also searched clinicaltrials.gov for pediatric clinical trials conducted in the same period and compared the numbers of studies on off-label use and clinical trials for the most commonly reported drugs and drug types. Our search revealed 568 studies on off-label drug use. Almost half of the studies (n = 240) were cross-sectional. A total of 212 specific drugs or drug types were addressed in 361 studies, the most frequent being antipsychotic agents (n = 12), dexmedetomidine (n = 10), and rituximab (n = 8). Antipsychotic agents were also the most common type of drug examined in clinical trials in children. We identified a total of 435 different types of off-label use, the top three being unapproved indication (n = 157), population (n = 96), or age (n = 36). Only about one-third of the studies reported collecting informed consent (n = 195) or having ethics committee approval (n = 166). Conclusions: Off-label use of antipsychotics in children is widely reported in the literature. We suggest pediatric researchers to consider the number of studies on off-label use and existing clinical trials on different drugs when selecting target drugs for new studies and systematic reviews. What is Known: • There exist a large number of studies on off-label drug use in children. What is New: • This is the first scoping review of studies on off-label drug use in children. • Off-label use of antipsychotic agents is widely reported.

BACKGROUND: Corona virus disease 2019 (COVID-19) showed a significant difference in case fatality rate between different regions at the early stage of the epidemic. In addition to the well-known factors such as age structure, detection efficiency, and race, there was also a possibility that medical resource shortage caused the increase of the case fatality rate in some regions. METHODS: Medline, Cochrane Library, Embase, Web of Science, CBM, CNKI, and Wan fang of identified articles were searched through 29 June 2020. Cohort studies and case series with duration information on COVID-19 patients were included. Two independent reviewers extracted the data using a standardized data collection form and assessed the risk of bias. Data were synthesized through description and analysis methods including a meta-analysis. RESULTS: A total of 109 articles were retrieved. The time interval from onset to the first medical visit of COVID-19 patients in China was 3.38±1.55 days (corresponding intervals in Hubei province, non-Hubei provinces, Wuhan, Hubei provinces without Wuhan were 4.22±1.13, 3.10±1.57, 4.20±0.97, and 4.34±1.72 days, respectively). The time interval from onset to the hospitalization of COVID-19 patients in China was 8.35±6.83 days (same corresponding intervals were 12.94±7.43, 4.17±1.45, 14.86±7.12, and 5.36±1.19 days, respectively), and when it was outside China, this interval was 5.27±1.19 days. DISCUSSION: In the early stage of the COVID-19 epidemic, patients with COVID-19 did not receive timely treatment, resulting in a higher case fatality rate in Hubei province, partly due to the relatively insufficient and unequal medical resources. This research suggested that additional deaths caused by the out-of-control epidemic can be avoided if prevention and control work is carried out at the early stage of the epidemic.

Background: Exercise and physiotherapy are accepted as an important contribution to the rehabilitation of patients with heart failure with preserved ejection fraction (HFpEF). But the previous results are unclear partly because of their limited power and small sample sizes. Aims: We aimed to understand better the effects of two exercise training interventions and two modalities of physiotherapies on exercise capacity, quality of life (QoL), and diastolic dysfunction in HFpEF patients. Methods: The Cochrane Library, EMBASE, and MEDLINE via PubMed were searched for randomized controlled trials from their inception to May 2021. The effect size was estimated as mean differences (MD) with 95% confidence intervals (CI). Results: A total of 14 articles on 13 trials were included in this meta-analysis with 673 HFpEF patients. The pooling revealed that peak oxygen uptake was improved by endurance training, functional electrical stimulation (FES), and inspiratory muscle training (IMT). Similar results were observed for a 6-minute walk test and QoL. A combination of endurance and resistance training (combined exercise) was beneficial to the ratio of peak early to late diastolic mitral inflow velocities (MD [95% CI]: –2.90 [–4.97, –0.83]; P = 0.006) and the early diastolic mitral annual velocity (MD [95% CI]: 1.40 [0.68, 2.12]; P = 0.006]. IMT improved the ventilation/carbon dioxide ratio slope (MD [95% CI]: –3.36 ml/kg/min [–6.17, –0.54]; P = 0.019]. Conclusions: FES and IMT improve functional capacity and QoL without a change in diastolic function in HFpEF patients, and the outcomes are similar to endurance training. Notably, combined exercise may improve diastolic function. Key words: diastolic function, exercise training, functional electrical stimulation, heart failure with preserved ejection fraction, inspiratory muscle training

ObjectivesTo analyze the effectiveness and quality of stroke clinical practice guidelines (CPGs) published in recent years in order to guide future guideline developers to develop better guidelines.ParticipantsNo patient involvedMethodPubMed, China Biology Medicine (CBM), Wanfang, CNKI, and CPG-relevant websites were searched from January 2015 to December 2019 by two researchers independently. The RIGHT (Reporting Items for Practice Guidelines in Healthcare) checklist was used to assess the reporting quality in terms of domains and items. Then, a subgroup analysis of the results was performed.Primary and secondary outcome measuresRIGHT checklist reporting rateResultsA total of 66 CPGs were included. Twice as many CPGs were published internationally as were published in China. More than half were updated. Most CPGs are published in journals, developed by societies or associations, and were evidence-based grading. The average reporting rate for all included CPGs was 47.6%. Basic information got the highest (71.7% ± 19.7%) reporting rate, while review and quality assurance got the lowest (22.0% ± 24.6%). Then, a cluster analysis between countries, publishing channels, and institutions was performed. There were no statistically significant differences in the reporting quality on the CPGs between publishing countries (China vs. international), publishing channels (journals vs. websites), and institutions (associations vs. non-associations).ConclusionsCurrent stroke CPGs reports are of low quality. We recommend that guideline developers improve the quality of reporting of key information and improve the management of conflicts of interest. We recommend that guideline developers consider the RIGHT checklist as an important tool for guideline development.Trial registration10.17605/OSF.IO/PBWUX.

ObjectivesTo synthesise current evidence from systematic reviews (SRs) regarding the efficacy and safety of non-pharmacological interventions to prevent and treat pain in newborn infants.DesignOverview of SRs.Data sourcesWe searched PubMed, Embase, Cochrane Library, Web of Science, CINAHL, Chinese National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), Wanfang Database, Chinese Science and Technology Periodical Database (VIP) and Google Scholar to identify all relevant SRs published in the last 5 years.Eligibility criteria for selecting studiesWe included SRs that evaluated the efficacy and safety of non-pharmacological interventions for neonatal pain.Data extraction and synthesisTwo reviewers independently extracted the data, assessed the methodological quality using a Measurement Tool to Assess Systematic Reviews (AMSTAR) 2 and graded the evidence quality with the Grading of Recommendations Assessment, Development and Evaluation (GRADE).ResultsA total of 29 SRs were included in this overview, of which 28 focused on procedural pain and only 1 focused on postoperative pain. Based on AMSTAR 2, seven reviews were found to be of ‘high quality‘, eight of ‘moderate quality’, five of ‘low quality’ and nine of ‘critically low quality’. The GRADE results suggested that facilitated tucking, kangaroo care, sweet solutions, familiar odour or combined non-pharmacological interventions, such as a combination of sucrose and non-nutritive sucking, were effective and safe in reducing pain from medical procedures in neonates. However, sucrose alone was less effective than local anaesthesia or a combination of the two during circumcision.ConclusionsFacilitated tucking, small volumes of sweet solutions, kangaroo care and familiar odour were recommended. Scientific implementation strategies should be developed to promote the clinical use of these effective non-pharmacological interventions. Meanwhile, further rigorous trials and SRs are needed to identify the best non-pharmacological approaches for pain from common surgery and illnesses in neonates.PROSPERO registration numberCRD42021292583.

Objective Since the beginning of the COVID‐19 epidemic, a large number of guidelines on diagnosis and treatment of COVID‐19 have been developed, but the quality of those guidelines and the consistency of recommendations are unclear. The objective of this study is to evaluate the quality of the diagnosis and treatment guidelines on COVID‐19 and analyze the consistency of the recommendations of these guidelines. Methods We searched for guidelines on diagnosis and/or treatment of COVID‐19 through PubMed, CBM, CNKI, and WanFang Data, from January 1, 2020 to August 31, 2020. In addition, we also searched official websites of the US CDC, European CDC and WHO, and some guideline collection databases. We included diagnosis and/or treatment guidelines for COVID‐19, including rapid advice guidelines and interim guidelines. Two trained researchers independently extracted data and four trained researchers evaluated the quality of the guidelines using the AGREE II instruments. We extracted information on the basic characteristics of the guidelines, guideline development process, and the recommendations. We described the consistency of the direction of recommendations for treatment and diagnosis of COVID‐19 across the included guidelines. Results A total of 37 guidelines were included. Most included guidelines were assessed as low quality, with only one of the six domains of AGREE II (clarity of presentation) having a mean score above 50%. The mean scores of three domains (stakeholder involvement, the rigor of development and applicability) were all below 30%. The recommendations on diagnosis and treatment were to some extent consistent between the included guidelines. Computed tomography (CT), X‐rays, lung ultrasound, RT‐PCR, and routine blood tests were the most commonly recommended methods for COVID‐19 diagnosis. Thirty guidelines were on the treatment of COVID‐19. The recommended forms of treatment included supportive care, antiviral therapy, glucocorticoid therapy, antibiotics, immunoglobulin, extracorporeal membrane oxygenation (ECMO), convalescent plasma, and psychotherapy. Conclusions The methodological quality of currently available diagnosis and treatment guidelines for COVID‐19 is low. The diagnosis and treatment recommendations between the included guidelines are highly consistent. The main diagnostic methods for COVID‐19 are RT‐PCR and CT, with ultrasound as a potential diagnostic tool. As there is no effective treatment against COVID‐19 yet, supportive therapy is at the moment the most important treatment option.

Background The "Law on Doctors of the People's Republic of China," which was officially implemented on March 1, 2022, emphasizes the requirements for rational drug use and the necessity for appropriate management of off-label drug use. The safety and ethical considerations related to off-label drug use are different in children than in adults. There is so far no management guideline for pediatric off-label use of drugs in China, and the applicability of foreign guidelines is limited. Establishing a localized evidence-based management guideline for pediatric off-label use of drugs to support the national legislation and clinical practice is of critical importance. Methods We established a guideline working group, including experts from a broad range of disciplines and developed recommendations following the guidance of the World Health Organization Handbook and the Chinese Medical Association. The following themes were identified by questionnaires and expert interviews to be of great concern in the management of off-label drug use in children: general principles and characteristics of management of pediatric off-label drug use; establishment of expert committees; evidence evaluation; risk–benefit assessment; informed consent; monitoring and assessment of the risk; and monitoring and patient education. Two rounds of Delphi surveys were organized to determine the final recommendations of this guideline. We graded the recommendations based on the body of evidence, referring to the evaluation tool of the Evidence-based management (EBMgt) and the Oxford Center for Evidence-Based Medicine: Level of Evidence (March 2009). Results We developed the first guideline for the management of pediatric off-label use of drugs in China. Conclusions The guideline is to offer guidance for pediatricians, pharmacists, medical managers, policymakers, and primary care physicians on how to manage off-label drug use in pediatrics and to provide recommendations for Chinese healthcare policy in the future.

Background Several antiviral agents licenced for blocking mother-to-child transmission (MTCT) of HBV, but their relative efficacy beginning from different trimesters has scarce been evaluated. We aimed to conduct a network meta-analysis to statistically differ the efficacy and safety of each antiviral agents initiating on different timings in preventing mother-to-infant transmission of HBV. Methods Studies were included from PubMed, EMBASE, Web of Science, and Cochrane databases through July 1, 2019. Eligible studies recruited randomized controlled trials and nonrandomized studies reporting about infant or/and maternal efficacy and safety outcomes and were screened by two investigators independently. Extracted data were analyzed by pair-wised and network meta-analysis, respectively. Results 3 Randomized and 32 nonrandomized studies enrolling 6738 pregnant female were included. Using network analysis, any antiviral agent interrupted HBV vertical transmission much more effectively than placebo. No agent showed significant efficacy different from others, but a strong trend toward significance was found in telbivudine and tenofovir, of which had the highest probability of being ranked the first- or second-best treatment for reducing MTCT of HBV. The treatment applied in the first and second trimester had a similar efficacy in preventing MTCT. Compared with the initiation during the third trimester, lower rate of MTCT was revealed when antiviral therapy was administrated before third trimester, (RR = 0.045, 95% CI 0.0053 to 0.20); a similar effect at delivery on suppressing maternal HBV DNA level and converting serum HBeAg were achieved if the timing of antiviral treatment started prior, but an obvious improvement of normalizing ALT flare was calculated out; no statistically differences among maternal and fetal safety outcomes were found if mothers received antiviral agents before pregnant 28 weeks. Conclusion This network meta-analysis recommended the earlier use of telbivudine or tenofovir, tends to be better to prevent MTCT of HBV in pregnancy with no increased adverse maternal or fetal outcomes.

Aim To describe the current status of COVID-19 vaccine guidelines. Study Design and Setting We searched databases, Google and guideline platforms to retrieve COVID-19 vaccine guidelines published between January 1, 2020 and July 8, 2021. We worked in pairs to identify the eligible guidelines and extract data of whether the methodology, funding, and conflict of interests were assessed/reported, and so on. Results were presented descriptively. Results A total of 106 COVID-19 vaccine guidelines were included. In the first half of 2021, on average 15 guidelines were published every month. Fifty (47.2%) guidelines addressed the vaccination of people with specific medical conditions, and 18 (17.0%) guidelines focused on adverse effects after vaccination. Only 28 (26.4%) guidelines reported the methodology they used. Four (3.8%) of guidelines assessed both the quality of evidence and strength of recommendations; 42 (39.6%) and 65 (61.3%) guidelines reported their funding sources and conflict of interest, respectively. Most guidelines were published in English (n=92, 86.8%). Conclusion A high number of guidelines on COVID-19 vaccines have been published in the recent months, but most of them lack clear and transparent reporting of methodology, funding, and conflicts of interest. Rigorous methodological and reporting quality evaluation of these guidelines is needed.

Coronavirus disease 2019 (COVID-19) has rapidly spread worldwide, but there is so far no comprehensive analysis of all known symptoms of the disease. Our study aimed to present a comprehensive picture of the clinical symptoms of COVID-19 using an evidence map.We systematically searched MEDLINE via PubMed, Web of Science, Embase, and Cochrane library from their inception to March 16, 2021. We included systematic reviews reporting the clinical manifestations of COVID-19 patients. We followed the PRISMA guidelines, and the study selection, data extraction, and quality assessment were done by two individuals independently. We assessed the methodological quality of the studies using AMSTAR. We visually presented the clinical symptoms of COVID-19 and their prevalence.A total of 102 systematic reviews were included, of which, 68 studies (66.7%) were of high quality, 19 studies (18.6%) of medium quality, and 15 studies (14.7%) of low quality. We identified a total of 74 symptoms including 17 symptoms of the respiratory system, 21 symptoms of the neurological system, 10 symptoms of the gastrointestinal system, 16 cutaneous symptoms, and 10 ocular symptoms. The most common symptoms were fever (67 studies, ranging 16.3%-91.0%, pooled prevalence: 64.6%, 95%CI, 61.3%-67.9%), cough (68 studies, ranging 30.0%-72.2%, pooled prevalence: 53.6%, 95%CI, 52.1%-55.1%), muscle soreness (56 studies, ranging 3.0%-44.0%, pooled prevalence: 18.7%, 95%CI, 16.3%-21.3%), and fatigue (52 studies, ranging 3.3%-58.5%, pooled prevalence: 29.4%, 95%CI, 27.5%-31.3%). The prevalence estimates for COVID-19 symptoms were generally lower in neonates, children and adolescents, and pregnant women than in the general populations.At least 74 different clinical manifestations are associated with COVID-19. Fever, cough, muscle soreness, and fatigue are the most common, but attention should also be paid to the rare symptoms that can help in the early diagnosis of the disease.

ImportanceDeveloping core outcome sets is essential to ensure that results of clinical trials are comparable and useful. A number of core outcome sets in pediatrics have been published, but a comprehensive in-depth understanding of core outcome sets in this field is lacking.ObjectiveTo systematically identify core outcome sets in child health, collate the diseases to which core outcome sets have been applied, describe the methods used for development and stakeholder participation, and evaluate the methodological quality of existing core outcome sets.Evidence ReviewMEDLINE, SCOPUS, Cochrane Library, and CINAHL were searched using relevant search terms, such as clinical trials, core outcome, and children, along with relevant websites, such as Core Outcome Measures in Effectiveness Trials (COMET). Four researchers worked in teams of 2, performed literature screening and data extraction, and evaluated the methodological quality of core outcome sets using the Core Outcome Set–Standards for Development (COS-STAD).FindingsA total of 77 pediatric core outcome sets were identified, mainly developed by organizations or researchers in Europe, North America, and Australia and mostly from the UK (22 [29%]) and the US (22 [29%]). A total of 77 conditions were addressed; the most frequent International Classification of Diseases, 11th Revision category was diseases of the digestive system (14 [18%]). Most of the outcomes in pediatric core outcome sets were unordered (34 [44%]) or presented in custom classifications (29 [38%]). Core outcome sets used 1 or more of 8 development methods; the most frequent combination of methods was systematic review/literature review/scoping review, together with the Delphi approach and consensus for decision-making (10 [14%]). Among the 6 main types of stakeholders, clinical experts were the most frequently involved (74 [100%]), while industry representatives were rarely involved (4 [5%]). Only 6 core outcome sets (8%) met the 12 criteria of COS-STAD.Conclusions and RelevanceFuture quality of pediatric core outcome sets should be improved based on the standards proposed by the COMET initiative, while core outcome sets methodology and reporting standards should be extended to pediatric populations to help improve the quality of core outcome sets in child health. In addition, the COMET outcome taxonomy should also add items applicable to children.

More women postpone childbearing nowadays while female fertility begins to decline with advancing age. Furthermore, with the rolling out of the two-child policy, there is a huge demand for a second child for Chinese aged women. There are various assisted reproductive technology (ART) strategies applied for age-related infertility without solid evidence. On behalf of the Society of Reproductive Medicine, Chinese Medical Association, we would like to develop a Chinese guideline of ART strategies for age-related infertility. This guideline was produced following the recommendations for standard guidelines described in the 2012 WHO Handbook for guideline development. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework was also followed. A protocol was formulated and a Guideline Development Group was formed with specialists of reproductive medicine, methodologists from Chinese GRADE working group, and patient representative. Questions regarding the ART strategies for aged infertility were formulated and 8 most important ones were chosen to be structured in PICO format (Population, Intervention, Comparison, Outcomes). Comprehensive search and review of the literature were performed and the quality of the evidence was assessed and rated based on certain criteria and be categorized as high, moderate, low, or very low. Twenty-five recommendations were formulated among members of the Guidelines Development Group (Delphi method) basing on the overall quality of the evidence, in addition to the balance between benefits and harms, values and preferences, and resource implications. The final recommendations were agreed on by consensus during face-to-face meetings. This is the first Chinese practice guideline in reproductive medicine developed following the standard and scientific method.

Objective To assess the methodological and reporting quality of Chinese- and English -language systematic reviews and meta-analyses (SRs/MAs) published by Chinese authors between 2016 and 2018. Study Design and Setting We searched MEDLINE and Chinese Science Citation Database (CSCD) for SRs/MAs led by Chinese authors published between 2016 and 2018. We used random sampling to select 10% of the eligible SRs/MAs published in each year from CSCD, and then matched the same number of SRs/MAs in MEDLINE. Reporting quality was evaluated using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and methodological quality using the Assessment of Multiple Systematic Reviews (AMSTAR-2) tool. Stratified analyses were conducted to compare the differences of quality between Chinese- and English language SRs/MAs. Results We identified 336 SRs/MAs (168 in Chinese and 168 in English). The reporting quality in Chinese-language SRs/MAs was slightly lower than English-language SRs/MAs (mean PRISMA scores: 20.58 vs. 21.71 in 2016, 19.87 vs. 21.24 in 2017, and 21.29 vs. 22.38 in 2018). Less than half of both Chinese- and English-language SRs/MAs complied with item 5 (protocol and registration), item 7 (information sources), item 8 (search) and item 27 (funding)). The methodological quality in Chinese -language SRs/MAs was also slightly lower than English -language SRs/MAs (mean AMSTAR-2 scores: 8.07 vs. 9.36 in 2016; 9.21 vs. 10.26 in 2017; 8.86 vs. 9.28 in 2018). Three items (item 2: established a protocol; item 4: use a comprehensive literature search; and item 10: report the sources of funding) were adhered to by less than 10% of both Chinese- and English -language SRs/MAs. Only one (0.6%) Chinese-language SRs/MA and nine (5.4%) English-language SRs/MAs were rated as high methodological quality. Conclusion The reporting and methodological quality of English-language SRs/MAs conducted by authors from China between 2016 and 2018 were slightly better than those of Chinese -language SRs/MAs.

Background Chinese herbal medicine (CHM) is thought to be a potential intervention in the treatment of coronavirus disease (COVID-19). Purpose This study aimed to investigate the efficacy and safety of CHM or CHM combination therapy for COVID-19. Study design Systematic review and meta-analysis Methods We searched for relevant studies in the CNKI, CBM, Wanfang Data, PubMed, Cochrane Library, Embase, and other resources from their inception to April 15, 2020. Randomized controlled trials, cohort studies, and case-control studies on CHM or CHM combination therapy for COVID-19 were included. Meta-analysis was performed according to the Cochrane Handbook. Results Overall, 19 studies with 1474 patients were included. Meta-analysis showed that the overall clinical effectiveness (OR = 2.67, 95% CI 1.83-3.89, I2 = 0%), improvement in the CT scan (OR = 2.43, 95% CI 1.80-3.29, I2 = 0%), percentage of cases turning to severe/critical (OR = 0.40, 95% CI 0.24-0.67, I2 = 17.1%), reverse transcription-polymerase chain reaction (RT-PCR) negativity rate (OR = 2.55, 95% CI 1.06-6.17, I2 = 56.4%) and disappearance rate of symptoms (fever, cough, and fatigue) were superior by combined CHM treatment of COVID-19. However, there was no statistical difference between the two groups in terms of length of hospital stay (WMD = -0.46, 95% CI -3.87 - 2.95, I2 = 99.5%), and rate of adverse effects (OR = 1.21, 95% CI 0.48-3.07, I2 = 43.5%). The quality of evidence was very low to low. Conclusion The combined treatment of COVID-19 with Chinese and Western medicine may be effective in controlling symptoms and reducing the rate of disease progression due to low quality evidence.

Background The Reporting Items for Practice Guidelines in Healthcare (RIGHT) checklist was used to assess the reporting quality of 2009–2019 clinical practice guidelines (CPGs) regarding gout and hyperuricemia, aimed to improve the reporting quality of future guidelines. Methods We searched PubMed, the Chinese Biomedical Literature database, the Wanfang Database, and the China National Knowledge Infrastructure from January 2009 to June 2019 for guidelines regarding gout and hyperuricemia. We also searched the websites of guideline development organizations (the Guidelines International Network, the National Institute for Health and Clinical Excellence, the American College of Rheumatology, and the European League Against Rheumatism (EULAR)). Furthermore, supplementary guidelines reported in included articles were systematically searched, as well as Google Scholar. Results Seventeen guidelines were included, of which one was in Chinese and 16 were in English. The mean reporting rate of the 35 items specified was 14.9 (42.5%); only five CPGs (29.4%) had a reporting rate >50%. Of the 35 items, three were very frequently reported. The reporting proportion of the seven domains (basic information, background, evidence, recommendations, review and quality assurance, funding and declaration and management of interests, and other information) were 64.7%, 36.8%, 50.6%, 42.9%, 8.82%, 33.8%, and 31.4%, respectively. Conclusion The reporting quality of the present guidelines for gout and hyperuricemia is relatively poor. We suggest that the RIGHT reporting checklist should be used by CPG developers to ensure higher reporting quality of future guidelines.

We read with interest a meta-analysis (1) recently published in “Frontiers in Endocrinology” conducted by Zhang et al. In this study (1), Zhang and colleagues included eight randomized controlled trials (RCTs) comparing sodium-glucose cotransporter 2 inhibitors (SGLT2is) with placebo in patients with type 2 diabetes (T2D), and performed a meta-analysis to produce a pooled risk ratio (RR) and 95% confidence interval (CI) of SGLT2is versus placebo in reducing four cardiovascular endpoints. The authors in this study (1) concluded that SGLT2is would be an ideal choice for T2D patients with heart failure (HF) because they found that SGLT2is significantly reduced hospitalization for heart failure (HHF), major adverse cardiovascular events (MACE, a composite of cardiovascular death, myocardial infarction, or stroke), and cardiovascular death (CVD) versus placebo in T2D patients. On the other hand, they concluded that SGLT2is did not significantly affect all-cause death (ACD) because they produced the nonsignificant 95% CI of RR (SGLT2is versus placebo: RR 0.77, 95% CI 0.59-1.01) for ACD. In my opinion, these two conclusions are not rigorous. First, they cannot conclude that SGLT2is are an ideal choice for T2D patients with HF until they assess the efficacy of SGLT2is in this T2D subgroup of concomitant HF and identify the obvious effectiveness. Second, using RR as drug effect is not accurate enough; all the original studies included in the meta-analysis (1) used hazard ratio (HR) as drug effect and RR only contains the status of the occurrence of events, but fails to contain the time when events happen. HR, on the other hand, contains both. Thus, to validate and further extend the findings in the meta-analysis by Zhang et al. (1), we implemented this further quantitative synthesis study by carrying out a meta-analysis stratified by the status of HF based on the data of HRs and 95% CIs as reported in the original studies. Moreover, we additionally incorporated the recently published SOLOIST-WHF trial (2), in addition to the eight RCTs included in the study by Zhang et al. (1), because this trial (2) contributed to the relevant data of the T2D subgroup of concomitant HF.

To summarize the evidence from Traditional Chinese Medicine (TCM) practice in the treatment of coronavirus disease 2019 (COVID-19) and provide timely clinical practice guidance.The guidelines were developed in accordance with the World Health Organization rapid guideline process. The evidence on TCM for COVID-19 from published guidelines, direct and indirect published clinical evidence, first hand clinical data, and expert experience and consensus were collected. The grading of recommendations assessment, development and evaluation (GRADE) method was used to grade the evidence and make the recommendations.Based on the available evidence, the guidelines recommended 17 Chinese medicines for COVID-19: 2 Chinese herbal granules, 7 Chinese patent medicines, and 8 Chinese herbal injections.As the literature search was conducted on March, any subsequent versions of these guidelines require an up-to-date literature review. We hope that the evidence summary in these will be helpful in global efforts to address COVID-19.

The worldwide spread of the 2019 novel coronavirus has become a profound threat to human health. As the use of medication without established effectiveness may result in adverse health consequences, the development of evidence-based guidelines is of critical importance for the clinical management of coronavirus disease (COVID-19). This research presents methods used to develop rapid advice guidelines on treating COVID-19 with traditional Chinese medicine (TCM). We have followed the basic approach for developing WHO rapid guidelines, including preparing, developing, disseminating and updating each process. Compared with general guidelines, this rapid advice guideline is unique in formulating the body of evidence, as the available evidence for the treatment of COVID-19 with TCM is from either indirect or observational studies, clinical first-hand data together with expert experience in patients with COVID-19. Therefore, our search of evidence not only focuses on clinical studies of treating COVID-19 with TCM but also of similar diseases, such as pneumonia and influenza. Grading of recommendations assessment, development and evaluation (GRADE) methodology was adopted to rate the quality of evidence and distinguish the strength of recommendations. The overall certainty of the evidence is graded as either high, moderate, low or very low, and to give either “strong” or “weak” recommendations of each TCM therapy. The output of this paper will produce the guideline on TCM for COVID-19 and will also provide some ideas for evidence collection and synthesis in the future development of rapid guidelines for COVID-19 in TCM as well as other areas.

IntroductionIntra-abdominal infections (IAIs) are common surgical emergencies and cause a significant worldwide burden per year. Since the concept of intraoperative peritoneal lavage (IOPL) was proposed in 1905, it has been widely used in the surgery practice. However, the effectiveness of IOPL in patients with IAIs has always been controversial. Our objective is to identify whether it is beneficial to flush the abdominal cavity with saline in IAIs surgery through a comprehensive systematic review and meta-analysis.Methods and analysisThis protocol is reported in line with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. Electronic databases (including the Cochrane library, MEDLINE, EMBASE, Web of Science, etc) and clinical trial registry platforms will be searched from inception to 8 September 2019. Randomised controlled trials, quasi-randomised clinical trials and cohort studies comparing IOPL and suction alone in IAIs will be included. The primary outcomes are mortality and abscess rate. Two independent reviewers will screen literature, collect data and assess risk of bias of included studies. Discussion or a third reviewer will be referred for any disagreements. The Grading of Recommendations Assessment, Development and Evaluation approach will be used to assess the quality of the evidence. We will perform meta-analysis using random-effects model. Subgroup analysis, sensitivity analysis and publication bias will be conducted if data are enough.Ethics and disseminationEthical approval is not required for this systematic review and meta-analysis protocol. Results of this study will be published in a peer-reviewed journal, presented at relevant conferences and disseminated to local and international policy makers.PROSPERO registration numberCRD42019145109.

Background In December 2019, a pneumonia caused by a novel coronavirus (SARS-CoV-2) emerged in Wuhan, China and has rapidly spread around the world since then. Aim This study aims to understand the research gaps related to COVID-19 and propose recommendations for future research. Methods We undertook a scoping review of COVID-19, comprehensively searching databases and other sources to identify literature on COVID-19 between 1 December 2019 and 6 February 2020. We analysed the sources, publication date, type and topic of the retrieved articles/studies. Results We included 249 articles in this scoping review. More than half (59.0%) were conducted in China. Guidance/guidelines and consensuses statements (n = 56; 22.5%) were the most common. Most (n = 192; 77.1%) articles were published in peer-reviewed journals, 35 (14.1%) on preprint servers and 22 (8.8%) posted online. Ten genetic studies (4.0%) focused on the origin of SARS-CoV-2 while the topics of molecular studies varied. Nine of 22 epidemiological studies focused on estimating the basic reproduction number of COVID-19 infection (R0). Of all identified guidance/guidelines (n = 35), only ten fulfilled the strict principles of evidence-based practice. The number of articles published per day increased rapidly until the end of January. Conclusion The number of articles on COVID-19 steadily increased before 6 February 2020. However, they lack diversity and are almost non-existent in some study fields, such as clinical research. The findings suggest that evidence for the development of clinical practice guidelines and public health policies will be improved when more results from clinical research becomes available.

Objective Stroke is the leading cause of death and disability in China. Chinese medicine integrated with conventional medicine is now widely used in the prevention and treatment of stroke. A clinical practice guideline for the application of integrative medicine in stroke is urgently needed. Methods This guideline was developed following the methodology and procedures recommended in the World Health Organization Handbook for Guideline Development and the Guideline Development Handbook for Diagnosis and Therapy of Integrative Medicine. The quality of evidence and strength of recommendations were evaluated using the GRADE approach. The guideline followed the RIGHT statement and AGREE II was consulted to ensure its quality. Results A multidisciplinary working team was established. Eleven research questions from 15 clinical questions were identified by questionnaire surveys, face-to-face meetings, and analyzed by the working team. Fourteen recommendations regarding integrative medicine for ischemic stroke, hemorrhagic stroke, and complications of stroke were formulated from systematic reviews of the benefits, harms, cost-effectiveness, quality of evidence, the values and preferences of patients and their family members, feedback on proposed recommendations from medical practitioners from a variety of disciplines, and a face-to-face consensus meeting. Conclusions This guideline focuses on clinical treatments that are specific to integrative medicine for stroke and can be used at all levels in medical institutions and rehabilitation facilities. The end-users of the guideline are most likely to be medical practitioners, including Chinese herbal medicine specialists, acupuncturists, integrative medicine practitioners, physicians, physical therapists, and clinical pharmacists.

Aims. To investigate the effect of preoperative HbA1c levels on the postoperative outcomes of coronary artery disease surgery in diabetic and nondiabetic patients. Methods and Results. The MEDLINE (via PubMed), Cochrane Library, Web of Science, Embase, Wanfang Data, China National Knowledge Infrastructure (CNKI), and Chinese Biology Medicine (CBM) databases were used to search the effects of different preoperative HbA1c levels on the postoperative outcomes of coronary artery disease surgical treatment in diabetic and nondiabetic patients from inception to December 2018. Two review authors worked in an independent and duplicate manner to select eligible studies, extract data, and assess the risk of bias of the included studies. We used a meta-analysis to synthesize data and analyze subgroups, sensitivity, and publication bias as well as the GRADE methodology if appropriate. The literature search retrieved 886 records initially, and 23 cohort studies were included in the meta-analysis. In this meta-analysis, we found that there was a reduced incidence of surgical site infections (OR=2.94, 95% CI 2.18-3.98), renal failure events (OR=1.63, 95% CI 1.13-2.33), and myocardial infarction events (OR=1.69, 95% CI 1.16-2.47), as well as a shortened hospital stay (MD=1.08, 95% CI 0.46-1.71), in diabetic patients after coronary artery disease surgical treatment with lower preoperative HbA1c levels. For nondiabetic patients, a higher preoperative HbA1c level resulted in an increase in the incidence of mortality (OR=2.23, 95% CI 1.01-4.90) and renal failure (OR=2.33, 95% CI 1.32-4.12). No significant difference was found between higher and lower preoperative HbA1c levels in the incidence of mortality (OR=1.06, 95% CI 0.88-1.26), stroke (OR=1.49, 95% CI 0.94-2.37), or atrial fibrillation (OR=0.94, 95% CI 0.67-1.33); the length of ICU stay (MD=0.20, 95% CI -0.14-0.55); or sepsis incidence (OR=2.49, 95% CI 0.99-6.25) for diabetic patients or for myocardial infarction events (OR=1.32, 95% CI 0.27-6.31) or atrial fibrillation events (OR=0.99, 95% CI 0.74-1.33) for nondiabetic patients. The certainty of evidence was judged to be moderate or low. Conclusion. This meta-analysis showed that higher preoperative HbA1c levels may potentially increase the risk of surgical site infections, renal failure, and myocardial infarction and reduce the length of hospital stay in diabetic subjects after coronary artery disease surgical treatment and increase the risk of mortality and renal failure in nondiabetic patients. However, there was great inconsistency in defining higher preoperative HbA1c levels in the studies included; we still need high-quality RCTs with a sufficiently large sample size to further investigate this issue in the future. This trial is registered with CRD42019121531.

BACKGROUND AND OBJECTIVE Critical clinical questions regarding how soon and how long the analgesic effect will be achieved by acupuncture, as well as who will be responsive to acupuncture, need further address. The aim of the study was to investigate the response-time relationship and covariate effects of acupuncture. DATABASES AND DATA TREATMENT PubMed and EMBASE were searched up to December 2018 for randomized controlled trials that involved sham acupuncture, true acupuncture and conventional therapy. We used a model-based longitudinal meta-analysis to characterize the response-time profile of these treatments. RESULTS Seventy-seven randomized clinical trials involved chronic shoulder, neck, knee and low back pain were included. The response-time analysis suggested that the treatment duration of acupuncture will be 5 weeks or more to achieve 80% of maximum analgesic effect. Moreover a lower baseline pain intensity and the location of low back pain resulted in a lower pain relief of acupuncture intervention. The absolute maximum analgesic effects of sham acupuncture and conventional therapy were 22.6 and 15.8 points at a 0-100 NRS scale. The absolute effect of true acupuncture was 26.1 points for low back pain (relative effect of 3.5 and 9.4 points to sham and conventional therapy), 34.9 points for other pain body locations (relative effect of 12.3 and 19.1 points to sham and conventional therapy), in patients with a baseline pain intensity of 60 points. CONCLUSION The treatment duration of acupuncture will not be less than 5 weeks to achieve 80% maximum analgesic effect. Higher analgesic effect was related to higher baseline pain intensity and pain location of neck, shoulder and knee. SIGNIFICANCE Our systematic review and meta-analysis provides the clear evidence for the treatment duration and significant related covariates of acupuncture intervention for chronic pain. These results provide useful suggestion for acupuncture intervention in clinical pain management.

Traditional Chinese medicine has been used for the treatment of many diseases including acute infections often associated with public health emergencies for thousands of years. However, clinical evidence supporting the use of these treatments is insufficient, and the mechanism for using Chinese medicine therapy in the public health setting has not been fully established. In this report, the Evidence-based Traditional and Integrative Chinese medicine Responding to Public Health Emergencies Working Group proposed five recommendations to facilitate the inclusion of Chinese medicine as part of our responses to public health emergencies. It is expected that the Working Group’s proposals may promote the investigation and practice of Chinese Medicine in public health settings.

ObjectiveThe aim of this study was to systematically evaluate the quality of the clinical practice guidelines (CPGs) for diabetes mellitus published in China over the period of January 2007 to April 2017.MethodsWe searched the China National Knowledge Infrastructure, Chinese Biomedical Literature database, VIP database and WanFang databases and guideline websites for CPGs for diabetes mellitus published between January 2007 and April 2017 in China. Two reviewers independently screened the literature according to the inclusion and exclusion criteria and extracted data. We used the the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool (Canadian Institutes of Health Research, Ottawa, Canada) to evaluate the quality of the included guidelines, calculated the scores of each domain and evaluated the consistency among the assessors via use of the intragroup correlation coefficient. And then we compared the results with Chinese CPGs and international CPGs. We conducted a subgroup analysis based on different classification criteria and compared scores of each domain subgroup analyses.ResultsA total of 98 guidelines were identified. The correlation coefficient within the group was 0.93, suggesting that the consistency between the evaluators was good. The scores of the six domains of AGREE II were described in median (IQR) as follows: scope and purpose 53.7 (50.0–59.7), stakeholder involvement 31.5 (27.3–37.0), rigour of development 19.1 (15.3–22.2), clarity of presentation 59.3 (50.0–64.8), applicability 18.1 (13.9–25.7) and editorial independence 0.0 (0.0–0.0). The mean score in each domain of quality of Chinese diabetes CPGs was lower than that of CPGs published worldwide but higher than the mean score of Chinese guidelines of all topics. A funding source, the updated version, organisation and publishers of the guidelines and target fields are all the factors influencing the quality of CPGs to a certain degree.ConclusionsA large number of Chinese diabetes CPGs have been produced. Their quality remain unsatisfactorily low compared with CPGs worldwide, there is still room for improvement. Chinese guideline developers should pay more attention to the transparency of methodology, and use the AGREE II instrument to develop and report guidelines.

Introduction In recent years, assisted reproductive technology (ART) has developed rapidly, leading to an increasing number of clinical practice guidelines in this field. However, the reporting quality of current clinical practice guidelines in ART is still unknown. Objective To evaluate the reporting quality of clinical practice guidelines in the field of ART using the RIGHT checklist. Method Relevant guidelines were identified by electronic search of PubMed, Chinese Biomedical Literature Database (CBM), Wan Fang Database and Chinese National Knowledge Infrastructure (CNKI) from the beginning of the database to October, 2017. We also searched the websites of the guideline development organizations, including Guidelines International Network (GIN), National Guideline Clearinghouse (NGC) and the National Institute for Health and Care Excellence (NICE), as well as from two medical associations, including the European Society of Human Reproduction and Embryology (ESHRE) and the American Society for Reproductive Medicine (ASRM). We used Google Scholar to find additional clinical practice guidelines (CPGs) as well. Two investigators searched the database, selected guidelines independently based on the inclusion criteria, and extracted the relevant information. Result Fifteen guidelines (i.e. six developed by individual institutions and 9 by associations) were included. On average, 12.7 out of 35 items in the RIGHT standard (36.3%) were reported in each guideline. Five items were not reported by any of these guidelines. The reporting proportion of the seven domains (i.e. Basic information; Background; Evidence; Recommendations; Review and quality assurance; Funding and declaration and management of interests; Other information) were 46.7%, 40.8%, 45.3%, 29.5%, 53.3%, 10.0%, 26.7%, respectively. Conclusion At present, the reporting quality of guidelines for ART is poor, especially regarding the funding. In the future guideline development, more consideration should be given to reporting, dissemination and implementation.

Background Inadequate planning, selective reporting, and incomplete reporting of outcomes in randomized controlled trials (RCTs) contribute to the problem of waste of research. We aimed to describe such a waste and to examine to what extent this waste could be avoided. Methods This research-on-research study was based on RCTs included in Cochrane reviews with a summary of findings (SoF) table. We considered the outcomes reported in the SoF tables as surrogates for important outcomes for patients and other decision makers. We used a three-step approach. (1) First, in each review, we identified, for each important outcome, RCTs that were excluded from the corresponding meta-analysis. (2) Then, for these RCTs, we systematically searched for registrations and protocols to distinguish between inadequate planning (an important outcome was not reported in registries or protocols), selective reporting (an important outcome was reported in registries or protocols but not in publications), and incomplete reporting (an important outcome was incompletely reported in publications). (3) Finally, we assessed, with the consensus of five experts, the feasibility and cost of measuring the important outcomes that were not planned. We considered inadequately planned or selectively or incompletely reported important outcomes as avoidable waste if the outcome could have been easily measured at no additional cost based on expert evaluation. Results Of the 2711 RCTs included in the main comparison of 290 reviews, 2115 (78%) were excluded from at least one meta-analysis of important outcomes. Every trial contributed to 55%, on average, of the meta-analyses of important outcomes. Of the 310 RCTs published in 2010 or later, 156 were registered. Inadequate planning affected 79% of these RCTs, whereas incomplete and selective reporting affected 41% and 15%, respectively. For 63% of RCTs, we found at least one missing important outcome for which the waste was avoidable and for 30%, the waste was avoidable for all important outcomes. Conclusions Most of the RCTs included in our sample did not contribute to all the important outcomes in meta-analyses, mostly because of inadequate planning or incomplete reporting. A large part of this waste of research seemed to be avoidable.

Background Hypertension is one of the common diseases, which brings heavy burden to human race. Currently, western medication is in absolutely dominant position in the treatment of hypertension, but it maintains for a short time and there are various side effects and drug tolerance. Therefore, Chinese medicine has attracted great attention in the treatment field of hypertension, and angelica is one of the most frequently used herbs. Objectives In order to give some inspiration to researches in these fields, this article presents the current research status of angelica and its compound formulas treating hypertension and its complications with evidence mapping. Methods Main databases were systematically searched, and researches about angelica or its compound formulas containing angelica treating hypertension or its complications were included. EXCEL 2013 was used to integrate and process the data, and the result is showed intuitively with the bubble diagram. Results 49 RCTs were included after screening. The articles recruited were published with a rising trend along with time. Of the 49 RCTs, there is the outcome measure of general the efficacy in the result part in 34 RCTs (69.4%), and all the clinical effective rate in the angelica intervention group is significantly higher than the control group. There is the outcome measure of reduction of MAP in the result part in 28 RCTs, and 27 RCTs (96.4%) showed that the angelica intervention group is significantly improved than the control group while 1 (3.6%) showed no significant differences. There is the outcome measure of efficacy of target organ protection in the result part in 26 RCTs, and 25 RCTs (96.2%) showed that there is significant difference between the angelica intervention group and the control group. Of the 49 RCTs, there is the outcome measure of adverse effects in the result part in 17 RCTs. 14 RCTs (82.4%) reported no adverse effects, 2 RCTs (11.8%) reported adverse effects rate as lower than 10%, and 1 RCT (7.1%) reported adverse effects rate as higher than 40%. Conclusion Current research with low quality has revealed that angelica is effective in reduction of MAP and target organ protection and the adverse effects rate is low, and the effectiveness and safety of angelica needs to be proved by further researches with high quality. Researches of high quality are needed to provide scientific evidence for angelica in treating hypertension and its complications.

ObjectivesWe systematically analysed recommendations from gout guidelines as an example, to provide a basis for developing a reporting standard of recommendations in clinical practice guidelines (CPGs).DesignSystematic review without meta-analysis.MethodsWe systematically searched MEDLINE and all relevant guideline websites (National Institute for Health and Care Excellence, National Guideline Clearinghouse, Scottish Intercollegiate Guidelines Network, WHO, Guidelines International Network, DynaMed, UpTodate, Best Practice) from their inception to January 2017 to identify and select gout CPGs. We used search terms such as ‘gout’, ‘hyperuricemia’ and ‘guideline’. We included the eligible CPGs of gout according to the predefined inclusion and exclusion criteria after screening titles, abstracts and full texts. The characteristics of recommendations reported in the included guidelines were extracted and analysed.ResultsA total of 15 gout guidelines with a range of 5–80 recommendations were retrieved. Several indicators were used in the gout guidelines to facilitate identification of recommendations, including grouping all recommendations in a summary section, formatting recommendations in a particular or special way, using locating words for recommendations and indicating the strength of recommendation and quality of evidence. We found some components commonly used in the recommendations. The wording of recommendations varied across guidelines. Recommendations were detailed and explained in the section of rationale and explanation of recommendations. In some guidelines, recommendations were accompanied with other material to assist their reporting.ConclusionsVariability and inconsistency were found on the reporting and presentation of recommendations in gout guidelines. Several points for reporting recommendation can be summarised. First, we suggested summarising and highlighting the core recommendations in a guideline. Second, guideline developers should try to structure and write recommendations reasonably. Third, it was necessary to detail and explain the recommendations and their rationale. Finally, describing and providing other potential useful contents was also a helpful way for clear reporting.

Objective The objective of this study was to conduct a meta-analysis of randomized controlled trials (RCT) to compare the effectiveness and safety of induction with and without antithymocyte globulin (ATG) combined with cyclosporine/tacrolimus-based immunosuppression in renal transplantation. Methods Trials were identified through a computerized literature search of PubMed, EMBASE, Cochrane controlled trials register, Cochrane Renal Group Specialized Register of RCTs, and Chinese Biomedical database. Two independent reviewers assessed trials for eligibility and quality, and then extracted data. Data were extracted for patient and graft survival, acute rejection, the incidence of Banff, cytomegalovirus (CMV) infection, leukopenia, and thrombocytopenia. Dichotomous outcomes were reported as relative risk (RR) with 95% confidence intervals (CI). Results Four RCTs (892 patients) were identified. The data showed that induction with ATG was more beneficial than no induction with ATG to reduce the incidence of chronic rejection (RR 0.70; 95% CI, 0.57–0.84) and acute rejection within 6 months (RR 0.68; 95% CI, 0.49–0.96) and at 12 months (RR 0.67; 95% CI, 0.50–0.89) as well as Banff II episodes (RR 0.53; 95% CI, 0.30–0.91), but increased the incidences of CMV infection (RR 1.61; 95% CI, 1.27–2.04) and leukopenia (RR 3.88; 95% CI, 2.80–5.38) and thrombocytopenia (RR 2.92; 95% CI, 1.77–4.04). There was no statistical difference between patient or graft survival rates at 6 and 12 months, as well as the incidences of Banff III or Banff I after transplantation. Conclusion Based on available data induction with ATG was more efficient to reduce the rate of acute rejection episodes and chronic rejection responses after renal transplantation, but was associated with increased side effects, particularly CMV infections. It is important to provide the most benefit for an individual patient.
