报告摘要:Meta-analysis is a statistical technique to synthesize the research findings from multiple studies for decision making. It has been increasingly popular in the past several decades, mainly due to its wide application in evidence-based practice. In meta-analysis, the two commonly used models include the common-effect model (CEM) and the random-effects model (REM). More recently, the fixed-effects model (FEM) is also recognized as an essential model for meta-analysis, especially when the number of studies is very small. FEM not only avoids the unrealistic assumption on a common effect in CEM when the heterogeneity exists, but also avoids the low estimation accuracy of the between-study variance in REM when there are only few studies. In this talk, I will give a brief introduction on some new developments related to meta-analysis with FEM, including the research outputs from our own group.
