Systematic Literature Review and Meta-Analysis: A Review

Abstract

Systematic reviews and meta-analyses are essential steps for summarizing and concluding the evidence accurately and reliably. They help to keep the evidence up-to-date. Based on the summary of evidence, policymakers can make judgments by analyzing the risk-benefit ratio of interventions. They also provide a basis for a starting point for clinical practice guideline developers and offer summaries of previous research for funders wishing to support new researchers.
