Beginning of meta-analysis in medical literature and its progression
Background: Meta-analysis is an epidemiological, recognized, quantifiable study design that helps in systematical evaluation of earlier research studies to originate conclusions indicative of the body of research. This paper provides an overview to meta-analysis and to highlight its rationales and a...

Background: Meta-analysis is an epidemiological, recognized, quantifiable study design that helps in systematical evaluation of earlier research studies to originate conclusions indicative of the body of research. This paper provides an overview to meta-analysis and to highlight its rationales and also over-all considerations related to meta-analysis. This article emphasizes on methods that are used in order to produce a demanding meta-analysis including various facets of staging and understandings of meta-analysis are deliberated.
