‘Systematic’ describes the review’s methods. It means that they are transparent, reproducible and defined before the search gets underway. That’s important because it helps to minimise the bias that would result from cherry-picking studies in a non-systematic way.
Literature reviews don’t usually apply the same rigour in their methods. That’s because, unlike systematic reviews, they don’t aim to produce an answer to a clinical question. Literature reviews can provide context or background information for a new piece of research. They can also stand alone as a general guide to what is already known about a particular topic.

Your supervisor may ask you to do a systematic review, when what they actually want you to do is a systematic review of the literature. There are a few key differences:
Systematic review | Systematic literature review |
---|---|
Brings together the results of studies to answer a specific question | Provides a subjective summary of the literature on a topic |
Extensive search covering published and grey literature | Thorough search of published literature |
Involves a detailed protocol often developed using the PICO framework | Includes a detailed search strategy |
Usually involves three or more people to eliminate bias | Can be produced by a single person, so open to bias |
Can take months or years to produce | Weeks or months to produce |
