What is a systematic review?
A systematic review is a type of literature review which seeks to collect, critically appraise, and synthesize all of the evidence answering a given research question. Meta-analysis is the statistical analysis conducted within a systematic review, combining the results of multiple studies.
Other types of literature reviews include:
- Scoping reviews – similar to a systematic review in scale and rigor, but aim to map all of the literature on a broad topic rather than addressing a narrow research question.
- Rapid reviews – completed within an accelerated time frame, rapid reviews typically do not include searches of the grey literature. Additional steps of the traditional systematic review may be modified or omitted to enable this shortened time frame.
