prisma 2020 checklist pdf: How to Find and Complete It

The prisma 2020 checklist pdf is a practical reporting aid for making a systematic review’s methods and findings easier to inspect. This guide shows how to find the official file, complete its location column against the review record, and check that the manuscript and flow diagram communicate what was done.

Use the checklist as a reporting check, not as a recipe for conducting a review or a score of its methodological quality. PRISMA 2020 supports transparent, complete reporting; it does not require a meta-analysis or establish that a review’s methods were appropriate. [1][7]

What do you need before starting?

Gather the current manuscript, protocol or registration record, search strategies and dates, screening and data-collection documentation, synthesis outputs, and any records of amendments. These are the source materials you will use to verify each checklist response, rather than relying on memory or the wording of the draft alone. PRISMA asks authors to report these kinds of details, including eligibility criteria, information sources, procedures, synthesis methods, limitations, registration, support, competing interests, and material availability. [3][4]

Decide who will check the completed checklist and how unresolved items will be reviewed. Automation can help locate candidate text or organize evidence, but the final entry should be checked against the review record by a responsible reviewer. A tool’s role should be reported where relevant; a suggested match is not proof that the manuscript fully addresses an item.

Step 1: Where can you download the official checklist?

Download the checklist from the PRISMA statement website or its linked PDF. The official checklist is a two-page PDF with space to record where each item is reported. The site also provides an editable Word file, an expanded checklist, an abstract checklist, flow-diagram templates, and a completion app; these resources serve different purposes, so do not mistake the checklist PDF for the entire PRISMA package. The checklists are distributed under CC BY 4.0. [2][3]

Choose the format that fits your workflow. The PDF is suitable for reviewing and recording locations; an editable file or completion app may be easier to update during manuscript revision. Consult the expanded checklist when you need fuller explanations of the items, and use the abstract checklist when checking an abstract. The flow-diagram templates support reporting review identification and selection, rather than replacing the main checklist. [2][4][5]

Why it matters: Using the official resource keeps the review anchored to the intended checklist and helps prevent omissions caused by an incomplete or altered copy.

Common mistake to avoid: Searching for “PRISMA PDF” and downloading a related but different resource without checking whether it is the main checklist, an expanded checklist, an abstract checklist, or a flow diagram.

Step 2: How should you complete the checklist?

Work through the checklist in order, using the manuscript and review records together. PRISMA 2020 has 27 numbered items, some with sub-items, organized across seven sections: title, abstract, introduction, methods, results, discussion, and other information. [1][3]

For each item, use a repeatable process:

• Read the item and any sub-items carefully.
• Find the manuscript passage that addresses it.
• Enter the precise page, section, table, figure, or supplement location in the checklist.
• Compare that passage with the underlying protocol, search files, screening records, analysis outputs, or other relevant documentation.
• If information is missing, incomplete, or inconsistent, flag it for the review team rather than marking it complete based on an assumption.

Treat a location as a pointer, not an endorsement. A page number shows where readers can find text; it does not establish that the text is sufficient or that the reported method was suitable. Where an item does not apply, record that clearly and give a brief reason if the form or submission process allows. Do not leave an unexplained blank that could be mistaken for an oversight.

A useful division of work is to have one person map manuscript locations and another verify them against the source record. If you use software to suggest relevant passages, check each suggestion manually and make the final decision accountable to the review team. This keeps automation in a supporting role and preserves a traceable link between the manuscript and the work performed.

Why it matters: The location column helps editors and readers navigate the report, while source-record checks reduce the risk that polished prose overstates or misrepresents what the team did.

Common mistake to avoid: Filling the checklist from the manuscript alone. A sentence may sound complete but conflict with the protocol, search history, or analysis record.

Step 3: What should you verify in the methods and results?

Check that the report explains how the review was designed and carried out, then verify that the results correspond to those methods. The checklist covers eligibility criteria, information sources and last search dates, full search strategies, screening and data-collection procedures, synthesis methods, and the reporting of results and uncertainty. It also asks for protocol and registration details, support, competing interests, and material availability. [3][4]

For each methods item, look for enough detail to let a reader understand what the team planned and did. Compare eligibility criteria with the stated review question and the screening record. Confirm that search dates and strategies correspond to the actual searches. Check that descriptions of screening, data collection, and synthesis match the documented procedures, including any changes made after the protocol.

For results items, compare the manuscript with the included-study dataset and analysis outputs. Verify that study-level findings and synthesis results are represented accurately, and that uncertainty is reported where relevant. If a decision or result is not documented, do not fill the gap by inference. Resolve the discrepancy, revise the manuscript, or state the limitation transparently.

Protocol and registration reporting deserves a separate check. The 2020 update clarified reporting of protocol and registration amendments, so compare the reported account with the protocol history and identify changes rather than implying that the original plan remained unchanged when it did not. [1][6]

Why it matters: A checklist is most useful when it tests the alignment between what the paper says and what the review team actually did—not merely whether a topic is mentioned.

Common mistake to avoid: Treating a brief mention as sufficient without checking whether the reader can understand the procedure, reproduce the search, or follow the reasoning behind the synthesis.

Step 4: What does the PRISMA flow diagram count?

Use the flow diagram to show how evidence moved through identification, screening, retrieval, exclusion, and inclusion. Select the template that matches the review: PRISMA provides variants for new versus updated reviews and for different types of information sources. [5][4]

Keep records, reports, and studies distinct. A record is a search result or citation; a report is a document that provides information about a study; a study is the underlying investigation. One study can have more than one report, so the number of reports is not necessarily the number of studies. For example, if multiple articles describe the same investigation, count the documents as reports and the underlying investigation as a study. This distinction helps prevent duplicate counting and makes the selection pathway interpretable.

Reconcile every flow-diagram figure with the screening and inclusion records. Check that records identified, screened, and excluded are accounted for; that reports sought and retrieved are represented; and that reasons for exclusions at the relevant stage are reported. Confirm that the final included evidence agrees with the manuscript’s study descriptions and synthesis.

Why it matters: Readers need to see how search results became included evidence and where exclusions occurred. Clear units and consistent counts make that path auditable.

Common mistake to avoid: Using “records,” “reports,” and “studies” interchangeably, or copying totals into the diagram without reconciling them to the review database.

Step 5: What changed in PRISMA 2020?

Use the 2020 checklist rather than assuming an older checklist covers the same reporting expectations. The update added or clarified topics including abstract reporting, protocol and registration amendments, detailed synthesis methods, certainty of evidence, and availability of data, code, and other materials. [1][6]

Pay particular attention to synthesis reporting. The updated checklist sets out detailed synthesis-method items, so check that the manuscript describes the methods used and the rationale for them, rather than relying on a broad statement that results were “pooled” or “summarized.” Also check that the abstract is assessed against the relevant guidance and that statements about certainty and available materials are supported by the review record. [1][3][6]

A checklist-completion study of 67 intervention reviews found low reporting of several items in that sample, including protocol amendments, certainty assessment, reporting-bias assessment, excluded-study details, and full search strategies. Those findings describe that sample and should not be generalized to all reviews or journals. [9]

Why it matters: Checking the updated topics can reveal omissions that are easy to miss when a team relies on an older template or familiar manuscript structure.

Common mistake to avoid: Treating the update as a cosmetic reformatting, or using one study of checklist completion as evidence that all reviews have the same reporting gaps.

Step 6: What does PRISMA ask you to report for a meta-analysis?

When a review includes meta-analysis, report the effect measures, synthesis methods and rationale, software, heterogeneity assessment, study-level results, and summary estimates with their precision. [3][4][8] Link each reported estimate to the analysis outputs and ensure the manuscript explains how the synthesis was performed.

PRISMA does not prescribe a particular statistical model, estimator, or heterogeneity method, and it does not require authors to pool results. [3][4][8] The checklist asks authors to make their choices and results transparent; it is not a statistical decision rule. If results are not pooled, report the synthesis approach used and explain it clearly rather than treating the absence of a pooled estimate as a checklist failure.

Check that the statistical account is internally consistent. The effect measure described should match the results presented; the stated software should match the analysis record; and the summary estimates and precision should agree with the outputs. Report heterogeneity assessment as performed, without implying that a statistic or model was mandated by PRISMA.

Why it matters: Transparent statistical reporting lets readers understand and assess the synthesis without confusing reporting guidance with a recommendation for one analysis.

Common mistake to avoid: Assuming that PRISMA requires a pooled analysis, or presenting a model choice as if the checklist had selected or endorsed it.

Step 7: What can a completed checklist—and automation—actually tell you?

A completed checklist can help readers find information and help authors identify reporting gaps. It cannot, by itself, show that the review used appropriate methods, that a synthesis is valid, or that the evidence is trustworthy. PRISMA is a reporting guideline, not a methodological-quality scoring tool or a review-conduct recipe. [1][7]

Use automation to support tasks such as locating candidate passages, mapping items to manuscript sections, or checking whether entries have been completed. Then verify the output against the manuscript and source records. Software may miss context, confuse a planned procedure with one actually performed, or suggest a match that does not fully answer the item. Keep reviewer judgment responsible for interpreting the evidence, resolving discrepancies, and approving the final checklist.

Before submission, perform a final cross-check: confirm every location, reconcile the flow diagram, check the manuscript against protocol and analysis records, and make sure relevant supplements or materials are available as described. The goal is a transparent account that a reader can follow—not a completed form treated as proof of quality.

Why it matters: Separating reporting completeness from methodological appraisal prevents the checklist from being used as a guarantee it was not designed to provide.

Common mistake to avoid: Treating a high completion rate, a software-generated match, or a filled-in checklist as validation of the review’s methods.
