WebFeb 10, 2011 · Meta-analyses use either a fixed effect or a random effects statistical model. A fixed effect meta-analysis assumes all studies are estimating the same (fixed) treatment effect, whereas a random … WebFor fixed effect meta-CART, weights are applied, and subgroup analysis is adapted. For random effects meta-CART, a new algorithm has been developed. The performance of the improved meta-CART was investigated via an extensive simulation study on different types of moderator variables (ie, dichotomous, nominal, ordinal, and continuous variables).
