Objectives: To investigate scientific collaboration and citation metrics of reporting guidelines for health research., Study Design and Setting: A cross-sectional analysis of published articles of reporting guidelines for health research. A search of the EQUATOR (Enhancing the QUAlity and Transparency Of health Research) Network Library (from inception to January 21, 2021) was supplemented by searching websites of guideline developers. For each article, metadata (e.g., authors, institutions, countries, citations) were extracted from the Web of Science and Scopus (up to October 25, 2021). Descriptive analyses were conducted. Network analyses of collaborations were presented., Results: We included 662 articles published in 332 journals. The BMJ (n = 50 articles; 8%), Annals of Internal Medicine (n = 29; 4%), and Journal of Clinical Epidemiology (n = 24; 4%) published the largest number of articles. Four thousand seven hundred twenty two authors, 1,647 institutions, and 83 countries were involved. The global productivity was led by the United States (n = 456 articles), the United Kingdom (n = 414), and Canada (n = 306). We found eight clusters of authors (e.g., one major group with 337 members) and three clusters of institutions (e.g., one major group with 256 members). The most prolific authors were affiliated with the Ottawa Hospital Research Institute (Canada), the University of Ottawa (Canada), the University of Oxford (the United Kingdom), and Stanford University (the United States)., Conclusion: Our analysis identified key actors producing reporting guidelines, most intense collaborations, and 'citation classics' in the field. These results could potentially be used to strengthen collaborations for developing and disseminating reporting guidelines for health research., (Copyright © 2023 Elsevier Inc. All rights reserved.)

The bioethics research conducted in Ibero-American countries has been very much restricted to its own realm. The aim of this study was to perform a bibliometric evaluation of bioethics papers by authors affiliated with Ibero-American institutions, and to determine how their work influences global bioethics literature. We performed a literature search in the Web of Science Core Collection (WoS CC) and Scopus. We identified a total of 5,975 documents, of which 84.3% were articles, 11.6% reviews and 4.1% book chapters. The median number of citations per paper was higher in English-language journals. Only 10 articles published between 2010 and 2019 in peer-reviewed bioethics journals and produced exclusively by authors from Ibero-American institutions garnered more than 15 citations. Our study suggests that if researchers from Ibero-American institutions want to influence global bioethical thinking, they must make the required leap in quality to be able to publish in high-quality bioethics and mainstream journals., (© 2021 John Wiley & Sons Ltd.)

The number of citations a peer-reviewed article receives is often used as a measure of its importance and scientific impact. This paper identifies, describes and categorizes the highly cited papers in addiction research on cannabis, heroin, cocaine and psychostimulants. Highly cited papers were identified in the Web of Science Core Collection database. Several bibliometric indicators were calculated. Social network analysis was applied to draw groups of authors and institutions with the greatest number of collaborations and co-words. The number of citations for the top 100 cited articles ranged from 649 to 4,672. The articles were published in 40 journals. The subject category Substance Abuse included 10 papers. The United States was the most productive country (79 papers), followed by the United Kingdom (9). The main funding institutions were the National Institutes of Health in the United States. The network of collaboration between authors distributes the 352 researchers into 53 groups. The three most cited works address the neural basis of drug craving as an incentive-sensitization theory of addiction, the clinical and research uses of the Addiction Severity Index, and the neurocircuitry of addiction. Scientific literature on addictions is widely dispersed both in multidisciplinary and specific journals of neurology, psychiatry and addictions, with relatively few publications providing most of the citations. An ongoing challenge for this field is the concentration of highly cited papers coming from a select number of countries, with the United States being the research hub of the world, with the highest volume of publications and total citations., (Copyright © 2021.
