12. Report and the PRISMA 2020 checklist¶
The review's PDF reports every item of the PRISMA 2020 checklist. What the review's own work says -- the criteria, the searches, the flow, how many reviewers worked and how, every analysis -- it writes itself. What only your team can say, you write on Report.

- Write each section: the rationale and objectives; the abstract's limitations and interpretation; the discussion; registration (or not registered), and why the protocol changed if it did; funding; competing interests; and what is publicly available. A section PRISMA needs and you have not written is outlined.
- Follow the checklist beside them: each of its 42 items reported or not yet. Items 21 and 22 are reported once you have judged each synthesis's missing results and certainty on Synthesis.
- Download the PDF. Its last appendix is the checklist, each item with the section and page reporting it. While any item is missing, every page says how many, so a draft is never mistaken for the finished report.
