Build a PRISMA 2020 completeness matrix by listing every checklist item, recording the manuscript location that addresses it, and flagging items that are missing or vague. PRISMA 2020 is a reporting checklist with an expanded checklist, an abstract checklist, and flow diagrams for original and updated systematic reviews. The matrix measures reporting completeness only; it does not score the review's methodological quality.
Build the matrix
- Create one row per PRISMA 2020 checklist item, including the abstract checklist items, and add columns for manuscript section, page or line, status (addressed, vague, missing), and the exact text or note that supports the status. Expected result: every item has a row and a status.
- Read each item's expanded-checklist guidance before judging the manuscript, then locate the passage that reports it. Expected result: you match items to the reporting they require, such as why the review was done, what methods were used, and what studies were found and included.
- Mark an item addressed only when the manuscript states the required information explicitly; mark it vague when the passage gestures at the topic without the specific content the item asks for. Expected result: vague and missing items are separated so you know which need new text and which need sharper text.
- Check the flow diagram against the studies the manuscript reports as found and included. Expected result: the diagram and the text describe the same set of studies, or the mismatch is logged as an open item.
- Convert each vague or missing row into a specific revision task naming the section to edit. Expected result: a prioritized to-do list tied to checklist items.
Keep the scope clear
A complete matrix shows that the review reports its rationale, methods, and study flow. It does not tell you whether the search strategy, risk-of-bias assessment, or synthesis was well designed. Keep those judgments in a separate appraisal so the completeness result is not read as a quality verdict.
Winter-health specifics
For a winter-health topic, confirm that the review's stated rationale and included-study reporting match the seasonal or population scope it claims. If the manuscript's scope statement and its included studies diverge, log that as a vague item and revise the scope wording or the study set.
