A systematic review is an article that reviews, or summarizes, many articles in one place. They often have ‘systematic review’ in the article title or within the abstract or introduction.
The Cochrane Handbooks defines a systematic review as:
"A systematic review attempts to collate all empirical evidence that fits pre-specified eligibility criteria in order to answer a specific research question. It uses explicit, systematic methods that are selected with a view to minimizing bias, thus providing more reliable findings from which conclusions can be drawn and decisions made(Antman 1992, Oxman 1993). The key characteristics of a systematic review are:
· a clearly stated set of objectives with pre-defined eligibility criteria for studies;
· an explicit, reproducible methodology;
· a systematic search that attempts to identify all studies that would meet the eligibility criteria;
· an assessment of the validity of the findings of the included studies, for example through the assessment of risk of bias; and
· a systematic presentation, and synthesis, of the characteristics and findings of the included studies.
You can find systematic reviews from the main search on the library homepage, CINAHL, the TRIP database, Cochrane Database of Systematic Reviews, and many more!
