CONSORT, STROBE & PRISMA Checklist Checker (Free)

Paste your manuscript and see which CONSORT 2025, STROBE, PRISMA 2020 or STARD items appear in the text and which are missing. In your browser, no account.

Paste your manuscript and see which items of the reporting guideline appear in the text and which do not. It detects whether it is a randomized trial, an observational study, a systematic review or a diagnostic accuracy study, picks the matching guideline and shows you, item by item, the sentence that supports it.

The text never leaves your browser: no account, nothing uploaded, nothing stored. For CONSORT, STROBE and PRISMA these are the same deterministic checks (no model) that Previum runs in the Professional Review; STARD, for now, is only checked here.

It only checks what a text search can decide: 6 of the 30 CONSORT 2025 items, 5 of the 22 STROBE items, 6 of the 27 PRISMA 2020 items and 8 of the 30 STARD 2015 items. The rest needs someone who reads.

Which items it checks in each guideline

• CONSORT 2025, 6 / 30: participant flow diagram (22a), blinding (or its declared absence) (20a), sample size calculation (16a), trial registration (2), losses to follow-up per arm (22b), inclusion and exclusion criteria (12a)
• STROBE, 5 / 22: inclusion and exclusion criteria (6a), sample size justification (10), sources of bias or confounding (9), missing data or losses to follow-up (12c), recruitment or data-collection period (5)
• PRISMA 2020, 6 / 27: search strategy (7), databases searched (6), risk-of-bias assessment (11), study-selection flow diagram (16a), protocol registration (24a), eligibility criteria and selection by two reviewers (5, 8)
• STARD 2015, 8 / 30: participant flow diagram (19), reference standard described (10b), blinding of test readers (13a, 13b), consecutive, random or convenience series (9), test positivity cut-off (12a), index test × reference standard cross-tabulation (23), indeterminate results (15), intended sample size (18)

The four guidelines, item by item

Each guideline has its own page with every item explained in plain words, what reviewers tend to object to in each block, and this same checker already set to it.

• CONSORT 2025 checklist: the 30 items, section by section
• STROBE checklist: the 22 items for observational studies, explained
• PRISMA 2020 checklist: the 27 items, section by section
• STARD 2015 checklist: the 30 items for diagnostic accuracy studies

What a checklist checker cannot see

• Whether the sample size calculation is right, and not merely mentioned.
• Whether the flow diagram numbers add up with the text and the tables.
• Whether the search strategy is reproducible rather than a list of words.
• Whether risk of bias was applied to each study, and not just named.
• Whether blinding is credible for that kind of intervention.
• Whether the analysis matches what was registered, and what changed along the way.
• Whether the conclusion rests on the primary outcome, and not on a secondary one.

Frequently asked questions

Which guideline applies to me?

CONSORT for randomized trials, STROBE for observational studies (cohort, case-control, cross-sectional), PRISMA for systematic reviews and meta-analyses, and STARD for diagnostic accuracy studies. The checker detects the design from the mentions in the body of the text; if it gets it wrong, pick it by hand.

Does it check the whole checklist?

No. Only the items a text search can decide: 6 of 30 in CONSORT 2025, 5 of 22 in STROBE, 6 of 27 in PRISMA 2020 and 8 of 30 in STARD 2015. The rest calls for a reader, and the page says so.

Why CONSORT 2025 and not CONSORT 2010?

Because the 2025 statement replaces the 2010 one and has 30 items, not 25. The six items the checker looks at are in both versions; what changes is the numbering and the total.

Does it upload my manuscript anywhere?

No. Everything runs in your browser with regular expressions; the text does not travel to any server and is not stored. If you later review it with Previum, it is processed there, under the tool’s confidentiality commitment.
