Empirical Comparisons of 12 Meta-analysis Methods for Synthesizing Proportions of Binary Outcomes
Lin, Lifeng; Xu, Chang; Chu, Haitao ( Springer , 2021 , Article)Background: Meta-analysis is increasingly used to synthesize proportions (e.g., disease prevalence). It can be implemented with widely used two-step methods or one-step methods, such as generalized linear mixed models ... -

We aimed ... -
Laplace approximation, penalized quasi-likelihood, and adaptive Gauss-Hermite quadrature for generalized linear mixed models: Towards meta-analysis of binary outcome with sparse data
Ju, Ke; Lin, Lifeng; Chu, Haitao; Cheng, Liang Liang; Xu, Chang ( BMC , 2020 , Article)© 2020 The Author(s). Background: In meta-analyses of a binary outcome, double zero events in some studies cause a critical methodology problem. The generalized linear mixed model (GLMM) has been proposed as a valid ... -
