Question and Answer
What is a systematic review?
A systematic review is research that assembles data from preexisting research to answer a specific question.
The process of collecting and analyzing the evidence follows specific methodological standards and guidance to reduce bias and thereby increase the reliability of the findings.
Cochrane states that a systematic review, “... attempts to identify, appraise and synthesize all the empirical evidence that meets pre-specified eligibility criteria to answer a specific research question."
