Meta-regression is simply the extension of the
regression analysis. Whereas in the regression
analysis, the outcome and the covariates
are measured for each subject, in meta-regression, the
outcome and the covariates are measured on the level
of the study. Because studies differ at least in the sample
size, we need to assign a weight in each study under a
specific model (fixed-effect or random-effects model)
before implementing a meta-regression analysis. Weight
assignment is not addressed in a regression analysis,
because we study subjects. The differences between
the regression and the meta-regression analysis are
obvious, but the goal is the same: to assess the association
between an outcome and one or more covariates.
