Abstract

Systematic review and meta-analysis is a research method that tries to provide the best evidence by comprehensive searching, combining of results, and evaluating methodological quality of studies focused on the undetermined clinical question. By keeping credibility of the research process and minimizing potential bias, authors can provide precise pooled estimates. Recently, meta-analysis publications have been increasing and there is a need for critical appraisal of this flow. This review aims to provide an overview of recent trends of meta-analysis in the upper gastrointestinal diseases by quantitative and qualitative analysis.

Key Words: Meta-analysis; Systematic review; Upper gastrointestinal tract
