What is a Systematic Review, and How Does it Differ from Other Reviews?

Typical attributes of a Systematic Review:

  • Contains a clearly stated set of objectives with pre-defined eligibility criteria for studies
  • Lists the databases that authors searched and the search terms they used
  • Authors assess the validity of the findings of the included studies, for example through the assessment of risk of bias
  • Systematically presents and synthesizes the characteristics and findings of the included studies -- frequently includes an evidence table

In a literature review, the authors aim to review the critical points of current knowledge including substantive findings as well as theoretical and methodological contributions to a particular topic, but do not necessarily follow a systematic process. 

You might also see "integrative review," which is a review that includes and synthesizes both experimental and nonexperimental research, such as qualitative studies.

Identifying Systematic Review Articles

Here's an example of an article that has Systematic Review as both a Minor Subject and as a Publication Type in the CINAHL database. For many citations, Systematic Review may appear in either the Publication Type or the Minor Subject but not always both fields.
