What PLOS Medicine requires
PLOS Medicine is a fully open-access general-medicine journal. It accepts a format-free initial submission, so structure rather than strict layout matters at first submission. Research articles use a structured abstract organised as Background, Methods and Findings, and Conclusions, with a preference for 300 words or fewer and a maximum of 500. PLOS Medicine enforces a strict data availability policy, requires prospective clinical trial registration and ethics statements, and uses Vancouver-style numbered references. CheckMyManuscript flags the presence and structure of these elements before submission.

PLOS Medicine is a fully open-access general-medicine journal with a format-free initial submission. Its research-article abstract is structured as Background, Methods and Findings, and Conclusions, preferably 300 words or fewer and no more than 500. It enforces a strict data availability policy, requires prospective trial registration and ethics statements, and uses Vancouver references. CheckMyManuscript screens your manuscript for the presence and structure of these elements before submission.
What CheckMyManuscript checks, and what it does not
CheckMyManuscript flags structural signals: an over-length or mis-structured abstract, a weak data availability statement, a missing trial registration number, or non-Vancouver references. It does not judge importance or methodological quality. Use the checker as a pre-submission completeness screen, not a compliance certificate.

What gets returned before review at PLOS Medicine
Common structural reasons manuscripts are returned at the editorial screen, each maps to a signal CMM can flag.
1.
Abstract over length or mis-structured
Abstract exceeds 500 words or is not in Background/Methods and Findings/Conclusions form.
CMM checks for: Structured abstract
2.
Weak data availability statement
A statement that does not meet the PLOS data policy.
CMM checks for: Data availability statement
3.
Trial registration missing
A randomised trial with no registration number.
CMM checks for: Trial registration
4.
References not Vancouver
References not in numbered Vancouver style.
CMM checks for: Vancouver references

The practical edge your peers already use
Across disciplines and career stages, researchers reduce bottlenecks and submit with confidence: clearer drafts, easier guideline compliance, and less back and forth with co‑authors and reviewers.
I use it to review my students' papers. It instantly highlights typos, missing references, and unclear sections, helping me focus my feedback on the quality of the research instead of surface errors.
Ilyass
Professor in Mechanical Engineering, ÉTS Montréal
I relied on it throughout my thesis to strengthen my writing. It suggested clearer phrasing, improved flow between sections, and ensured my references were complete before the final deadline.
Manon
Master's Student in Speech Therapy
I write research in both Portuguese and English, and it adapts perfectly to either language. It provided precise feedback in Portuguese, helping me maintain academic tone and consistency across my drafts.
Afonso
PhD Candidate, UFPE
It gave excellent advice on how to rephrase and present ideas more clearly and concisely. The suggestions helped me refine my arguments and make my research more impactful.
Félix
Postdoc Researcher, Max Planck Institute for Evolutionary Biology
A round of suggestions helped to generally refine the text of my paper and, moreover, to present some of its key points in a more focused form.

Frequently asked questions
PLOS Medicine research articles use a structured abstract with Background, Methods and Findings, and Conclusions, preferably 300 words or fewer and no more than 500 words. Abstracts that are over length or mis-structured are commonly queried.
Yes. PLOS Medicine accepts format-free initial submissions, so at first submission completeness and structure matter more than strict layout. Required statements such as data availability, ethics, and trial registration are still expected.
No. CheckMyManuscript checks the presence and structure of required elements such as the structured abstract, data availability, and references. It does not judge importance or methodological quality, and it does not replace peer review.
