-After fitting a random-effects model and finding heterogeneity in the observed effects, meta-analysts often want to examine whether one or multiple moderator variables (i.e., predictors) are able to account for the heterogeneity (or at least part of it). Meta-regression models can be used for this purpose. A question that frequently arises in this context is how to compute an 'adjusted effect' based on such a model. This tutorial describes how to compute such adjusted effects for meta-regression models involving continuous and categorical moderators.+After fitting a random-effects model and finding heterogeneity in the effects, meta-analysts often want to examine whether one or multiple moderator variables (i.e., predictors) are able to account for the heterogeneity (or at least part of it).
