"A systematic review attempts to collate all empirical evidence that fits pre-specified eligibility criteria in order to answer a specific research question. The key characteristics of a systematic review are: a clearly defined question with inclusion & exclusion criteria; rigorous & systematic search of the literature; critical appraisal of included studies; data extraction and management; analysis & interpretation of results; and report for publication." -- Duke University Medical Center Library & Archives
A systematic review differs from a traditional literature review or narrative review, in that it aims to be as thorough and unbiased as possible, and also provides detailed information about how the studies were identified and why they were included.
