What it means
Its strength is transparency: the search, selection and quality checks are reported so that others can repeat them. A systematic review is only as good as the studies it includes, so a review of small, weak trials can still be weak.
Look for a stated protocol, such as registration on PROSPERO, and for a note on study quality.
Also known as
- systematic literature review
- PRISMA review
- evidence review
