Evidence-Based Practice: Critical Appraisal Tools for Systematic Reviews/Meta-Analyses

This guide will help you work through the process of Evidence-Based Practice.

Defining Systematic Review/Meta-Analysis Study Design

"A Systematic Review is a comprehensive survey of a topic that takes great care to find all relevant studies of the highest level of evidence, published and unpublished, assess each study, synthesize the findings from individual studies in an unbiased, explicit and reproducible way and present a balanced and impartial summary of the findings with due consideration of any flaws in the evidence. On the other hand, Meta-analysis is a systematic, objective way to combine data from many studies, usually from randomized controlled clinical trials, and arrive at a pooled estimate of treatment effectiveness and statistical significance." (Koffel, 2011)
