Adjusting for publication bias in meta-analysis with continuous outcomes: a comparative study
Osama Almalik
Abstract Publication bias has been a problem facing meta-analysts. Methods adjusting for publication bias have been proposed in the literature. Comparative studies for methods adju…
Combining dependent p-values resulting from multiple effect size homogeneity tests in meta-analysis for binary outcomes
Osama Almalik
Testing effect size homogeneity is an essential part when conducting a meta-analysis. Comparative studies of effect size homogeneity tests in case of binary outcomes are found in t…
A bivariate likelihood approach for estimation of a pooled continuous effect size from a heteroscedastic meta-analysis study
Osama Almalik, Edwin R. van den Heuvel
The DerSimonian-Laird (DL) weighted average method has been widely used for estimation of a pooled effect size from an aggregated data meta-analysis study. It is mainly criticized…
Simulation Models for Aggregated Data Meta-Analysis: Evaluation of Pooling Effect Sizes and Publication Biases
Edwin R. van den Heuvel, Osama Almalik, Zhuozhao Zhan
Simulation studies are commonly used to evaluate the performance of newly developed meta-analysis methods. For methodology that is developed for an aggregated data meta-analysis, r…
Copas' method is sensitive to different mechanisms of publication bias
Osama Almalik, Zhuozhao Zhan, Edwin R. van den Heuvel
Copas' method corrects a pooled estimate from an aggregated data meta-analysis for publication bias. Its performance has been studied for one particular mechanism of publication bi…
