Abstract

Objective To provide a critical appraisal on the evidence from randomized controlled clinical trials (RCTs) on the utility of direct endovascular treatment (dEVT) compared to the combination of endovascular treatment preceded by IV thrombolysis (bridging therapy [BT]) for patients with acute large vessel occlusion (LVO). Methods Eligible RCTs were identified by searching Medline and Scopus. We calculated the corresponding odds ratios (ORs) and 95% confidence intervals (CIs) and pooled estimates using random-effects models. The primary outcome was the probability of modified Rankin scale (mRS) score of 0 to 2 at 3 months. Results We included 3 studies comprising 1,092 patients. No difference between the dEVT and BT groups was detected for the outcomes of mRS score of 0 to 2 (OR 1.08, 95% CI 0.85-1.38; adjusted OR 1.11, 95% CI 0.76-1.63), mRS score of 0 to 1 (OR 1.10, 95% CI 0.84-1.43; adjusted OR 1.16, 95% CI 0.84-1.61), and functional improvement at 3 months (common OR 1.08, 95% CI 0.88-1.34; adjusted common OR 1.09, 95% CI 0.86-1.37). Patients receiving dEVT had significantly lower likelihood of successful recanalization before the endovascular procedure compared to those receiving BT (OR 0.37, 95% CI 0.18-0.77). Patients receiving dEVT had lower intracranial bleeding rates compared to those receiving BT (OR 0.67, 95% CI 0.49-0.92) but without a significant difference in the probability of symptomatic intracranial hemorrhage. No differences in all-cause mortality, serious adverse events, or procedural complications between the 2 groups were uncovered. Conclusions We detected no differences in functional outcomes of IV thrombolysis-eligible patients with an acute LVO receiving dEVT compared to BT. Because uncertainty for most endpoints remains large and the available data are not able to exclude the possibility of overall benefit or harm, further RCTs are needed.

Abstract

This study examines the relationship between family and school characteristics, and student reading performance; and how these vary across countries with different levels of economic inequality and stratification. Economic inequality is measured with the Gini index and stratification by the distribution of students by reading achievements. Reading tests and questionnaire responses of 190,456 fourth-graders, their parents and 6,987 school administrators in 41 countries were analysed using multilevel analyses. Students with lack of early home literacy activities have better test scores in schools with higher average socioeconomic status (SES), and reading scores in countries with a high level of economic inequality. The higher the stratification level, the better student reading achievements, despite the stratification measure indicating the inequality of their distribution among schools
