Review vs Meta-Analysis

A review paper /literature review, provides a comprehensive overview and evaluation of existing research on a particular topic. It involves gathering information from multiple sources, such as research articles, books, and other relevant publications, and synthesizing the findings to summarize the current state of knowledge on the topic. Review papers typically do not involve statistical analysis or original data collection.

A meta-analysis is a specific type of research synthesis that involves combining and analyzing quantitative data from multiple studies to generate more robust conclusions. Researchers identify relevant studies, extract relevant data from each study, and statistically analyze the combined data to derive overall effect sizes or estimates of the relationship between variables. Meta-analyses often include a systematic review of the literature as a first step to identify relevant studies for inclusion.
