fixed effect meta-analysis假定所有研究都估计固定的treatment effect,然而random effects meta-analysis允许不同研究中的treatment effect 差异。 fixed effect和random effects meta-analyses的区别:如下图,95%置信区间的Forest plots,fixed effect meta-analysis提供了对common treatment effect的最好估计,fixed effect假定...
Fixed effects (Mantel-Haenszel) meta-analysisThomas Lumley
Meta-analysis里面的FE和RE分别对应于HLM的“固定斜率”和“随机斜率”,不过这里的“斜率”应理解为元分析不同Study的效应量。效应量本身可以看做是Level 1的斜率,而效应量的标准误则对应于Level 1(组内)的残差。总体来说,Meta-analysis大多采用RE模型(即HLM的随机斜率模型)。 参考文献 Borenstein, M., Hedges,...

In the meta-analysis setting, the adverse consequences of a false negative test are more profound than the disadvantages of a false positive test. Our alternative test improves the error rates in fixed effects meta-analysis. Its significance level equals the nominal value, and the Type II error...

Meta-analytic structural equation modeling (MASEM) combines the ideas of meta-analysis and structural equation modeling for the purpose of synthesizing correlation or covariance matrices and fitting structural equation models on the pooled correlation or covariance matrix.
