Introduction to systematic review and meta-analysis
A systematic review collects all possible studies related to a given topic and design, and reviews and analyzes their results [1]. During the systematic review process, the quality of studies is evaluated, and a statistical meta-analysis of the study results is conducted on the basis of their quality. A meta-analysis is a valid, objective, and ...
