Statistical meta-analysis and forest plot illustrating the effect of peer-assisted learning. In the forest plot, the pooled effect (solid diamond) summarizes the meta-analysis revealing a marginal but overall improvement in learning (Favours – experimental) using peer-assisted learning considering all studies together. Individual studies vary in their outcomes, but the majority either exhibit improvement, or little or no detriment to medical student learning. A Analysis of all 13 selected studies. B Analysis of studies omitting the study of Shah (2017)
