Which is better meta-analysis or systematic review?
It is a systematic review that uses quantitative methods to synthesize and summarize the results. An advantage of a meta-analysis is the ability to be completely objective in evaluating research findings. Not all topics, however, have sufficient research evidence to allow a meta-analysis to be conducted.
What is the difference between a systematic review and a meta-analysis?
A systematic review attempts to gather all available empirical research by using clearly defined, systematic methods to obtain answers to a specific question. A meta-analysis is the statistical process of analyzing and combining results from several similar studies.
