What is the difference between a literature review and a systematic review?
Answer
A literature, or narrative, review is an informal synthesis of information. It does not require reproducible methods and can be completed by a single author. Because of this, it is also more prone to bias. A literature review usually takes significantly less time to complete than a systematic review.
A systematic review is more focused and reproducible, as the goal is to bring in all available literature on a topic before screening it for relevant items, evaluating their quality, extracting the relevant data, and completing a qualitative and or quantitative analysis.
