For estimation of heterogeneity variance τ 2 in meta-analysis of log-odds-ratio, we derive new mean- and median-unbiased point estimators and new interval estimators based on a generalized Q statistic, Q F , in which the weights...

There are currently no abstract classifiers, which can be used for new diagnostic test accuracy (DTA) systematic reviews to select primary DTA study abstracts from database searches. Our goal was to develop machine-learning-based abstract c...
Comparison of statistical methods for integrating real-world evidence in a rare events meta-analysis of randomized controlled trials [0.03%]
罕见事件的随机对照试验荟萃分析中纳入真实世界证据的统计方法比较

Minghong Yao et al.
Rare events meta-analyses of randomized controlled trials (RCTs) are often underpowered because the outcomes are infrequent. Real-world evidence (RWE) from non-randomized studies may provide valuable complementary evidence about the effects...

We examine four important considerations in the development of covariate adjustment methodologies for indirect treatment comparisons. First, we consider potential advantages of weighting versus outcome modeling, placing focus on bias-robust...
Re-orientating systematic reviews to rigorously examine what works, for whom and how: Example of a realist systematic review of school-based prevention of dating and gender violence [0.03%]

Conventional systematic reviews offer few insights into for whom and how interventions work. 'Realist reviews' examine such questions via examining 'context-mechanism-outcome configurations' (CMOCs) but are insufficiently rigorous in how ev...

Analysts seldom include interaction terms in their meta-regression model, which can introduce bias if an interaction is present. We illustrate this by reanalysing a meta-regression study in acute heart failure. Based on a total of 285 studi...
