"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. The key characteristics of a systematic review are:
Many systematic reviews contain meta-analyses. Meta-analysis is the use of statistical methods to summarize the results of independent studies (Glass 1976). By combining information from all relevant studies, meta-analyses can provide more precise estimates of the effects of health care than those derived from the individual studies included within a review . They also facilitate investigations of the consistency of evidence across studies, and the exploration of differences across studies."

Systematic reviews are gaining in popularity at medical research institutions across the US. Mulford librarians have received advanced training to support systematic review creation and are available for collaboration and consultation and Mulford Library offers several resources and services to support systematic review research. All guidelines governing the creation of systematic reviews recommend the involvement of a librarian or information professional on your systematic review team.
This guide provides a step-by-step approach to conducting a systematic review. Each page shows which team members are involved at each step and suggests tools and resources that lead to a successful systematic review publication.
