Major Revision at BMJ Open: What It Means, Next Steps

The line that matters is whether your paper stays active in the open-review thread. A major revision keeps it active; a reject-and-resubmit closes the current file.

BMJ Open does not report an acceptance-after-major-revision rate, so any precise BMJ Open-specific number is invented. The defensible framing rests on three facts: the journal's overall acceptance rate is roughly 27 percent, which is higher than most selective journals because BMJ Open judges soundness rather than novelty; most acceptances follow at least one revision; and a major revision means the soundness gate is already largely passed.

• Reaching a major revision means you cleared the scope-fit and reporting desk screen and survived a first round of open review.

• Because BMJ Open does not gate on novelty, the path to acceptance is mostly about closing reporting and statistical gaps rather than proving importance.

• The general cross-journal figure that 60 to 80 percent of major revisions are eventually accepted is a reasonable prior here, and BMJ Open's soundness-not-novelty criterion makes a well-executed revision relatively likely to succeed.

A BMJ Open major revision is one of the more recoverable major-revision situations in clinical publishing, provided the revision closes the soundness and reporting concerns the reviewers named.

BMJ Open does not publish a standard revision window on its author pages, so use the deadline in your decision letter. BMJ Open reports a median of 134 days to first decision with review, so the first round can run long, and its author pages give no re-review time.

If the analyses will not fit the window, email info.bmjopen@bmj.com or use the manuscript submission system with your manuscript ID before the deadline; BMJ Open's contact page says the deadline can be extended on request, including after the original deadline has expired. The avoidable failure is missing the date silently.

Keep the revised paper within BMJ Open's display limit while you add the requested work: the author page gives no word limit for original research, asks for a structured abstract and no more than eight figures and tables, and says it may ask you to move material into supplementary files. Because BMJ Open is fully open access, plan for the article processing charge of 2,535 GBP (exclusive of VAT for UK and EU authors and GST for Australian and Indian authors), payable on acceptance, so a funder or institutional-agreement conversation belongs in the revision window rather than after a positive decision.

A revised BMJ Open manuscript goes back through the editorial process, and BMJ Open's author pages do not say who re-reviews it, so follow your decision letter. Where reviewers re-read it, review is open, so they can see and judge whether you engaged with their reports. They evaluate soundness and completeness, not novelty.

The BMJ Open response letter is a public-facing document under open peer review, so it must be rigorous, complete, and readable.

1. Executive summary first. Three to four sentences thanking the named editor and reviewers, stating that all concerns are addressed, and summarizing the headline changes.

1. Cite the comment, the change, and where it landed. For each comment, quote it, describe the change you made, and give the exact page, table, or line where it landed. Give statistical comments a dedicated crosswalk to the analysis plan.

1. Write for publication. Because reports and responses may be published, concede valid points cleanly and explain disagreements with literature support and courtesy.

1. Show soundness, not importance. BMJ Open does not gate on novelty, so the response should demonstrate that the study is now valid and completely reported, rather than argue that the result is a major breakthrough.

1. Submit a tracked-changes manuscript. Provide clean, tracked-changes, and point-by-point response files together.

Route your revised manuscript through a BMJ Open response-to-reviewers check so the reporting completeness and statistical-methods package are verified against the named reviewers' concerns before you resubmit.

• Do not write a defensive rebuttal. Under open review it becomes part of the record and invites a harder re-read.

• Do not leave a statistical concern unanswered. Statistics is one of the areas BMJ Open's review questions cover.

• Do not overstate clinical implication. BMJ Open judges soundness, not impact, so overclaiming reads as a reporting weakness.

• Do not promise changes the manuscript does not contain. Named reviewers verify the file.

• Do not let limitations, ethics, or data-availability statements read weakly in a record that may be published.

• Do not miss the deadline without contact.

Across BMJ Open-targeted manuscripts, three patterns most often turn a possible acceptance into a major revision, and the same three most often decide whether the revision then clears open peer review. These are anonymized observations from Manusights pre-submission and revision review, not access to BMJ editorial records. Each is a named failure pattern tied to a specific BMJ Open editorial expectation, and in practice we see them recur across the manuscripts we screen.

The useful question for a revising author is whether the revised reporting checklist, statistical methods, ethics statements, and open-review response letter already answer the reviewer concern in the manuscript itself.

Reporting-checklist gaps that become visible in a published record. In BMJ Open manuscripts, a frequent reason for a major revision is incomplete EQUATOR reporting: CONSORT, STROBE, or PRISMA items that point vaguely to the Methods instead of naming where each item is answered. Because BMJ Open publishes reviewer reports and pre-publication history for accepted papers, a thin reporting checklist is more exposed than it would be under closed review.

The strongest revisions answer each checklist item with an exact manuscript location and treat the checklist as a public-facing document, so the re-reviewing reader can verify completeness without reconstructing it.

Statistical-methods gaps that reviewers re-test. In BMJ Open manuscripts, reviewers re-check sample-size justification, multiple-testing adjustment, missing-data handling, subgroup analysis, and sensitivity analysis. A major revision frequently reads as sound-but-statistically-incomplete. The strongest revisions include an analysis-plan crosswalk, table shells that match the registered protocol, and explicit reasoning for every exclusion and deviation, all documented in the response so reviewers can confirm the fix directly rather than inferring it.

Open-review response letters that overstate or read as defensive. In BMJ Open manuscripts, because reviewer names and reports may be published alongside the accepted paper, the response letter carries reputational weight it does not at closed-review journals. The revision that struggles is usually the one whose letter overstates the clinical implication, argues with a named reviewer, or describes a change that is not actually in the manuscript.

Since BMJ Open judges soundness rather than novelty, a letter that quietly demonstrates validity and complete reporting, concedes valid points, and locates every change earns a smoother re-review than one that markets importance.

This page tells you what BMJ Open reviewers look for when they re-read a revised manuscript under open peer review. The review tells you whether YOUR revised paper and response letter pass that check before you resubmit. Use this page when you have just received a major revision at BMJ Open and need to decide what to strengthen before drafting the response.

We have reviewed manuscripts targeting BMJ Open and adjacent open-access clinical journals in pre-submission and revision contexts; the named patterns above are the same ones reviewers flag on re-review. 60-day money-back guarantee. Your manuscript is not used for model training, and access is limited to the review workflow.

Of the manuscripts our team reviewed for this BMJ Open decision-outcome pattern sample, the strongest predictor of a clean open-review re-review was whether the revised reporting checklist and statistical crosswalk answered each named reviewer concern with an exact manuscript location, rather than relying on a general assurance that the study was sound.

Check whether your BMJ Open revision is re-review ready

If a BMJ Open revision is rejected after re-review, the cascade depends on what the reviewers and editor cited.

BMJ Open specialty journals (BMJ Open Quality, BMJ Open Gastroenterology, BMJ Open Diabetes Research and Care, BMJ Open Respiratory Research, and similar) are natural BMJ cascades where the specialty editorial scope fits, and BMJ supports transfer with reviewer reports preserved.

External open-access cascades include PLOS ONE, BMC Medicine, and Scientific Reports for sound work that fits a broad open-access scope; reports do not transfer, but a documented BMJ Open revision strengthens a fresh submission.

This page was created from BMJ Open public author and peer-review documentation at bmjopen.bmj.com, the broader peer-review literature on major-revision handling and response-letter structure, and Manusights pre-submission and revision review experience with BMJ Open-targeted manuscripts.

Source limitations: BMJ Open publishes the open-peer-review model, the soundness-not-novelty criterion, a 27% acceptance rate and median decision times, but it does not publish a journal-specific acceptance-after-major-revision rate. Any precise BMJ Open-specific revision-acceptance percentage is therefore not verifiable; the 60 to 80 percent figure above is a general cross-journal range, not a BMJ Open number.

The named revision patterns are Manusights interpretation from pre-submission and revision review, not private BMJ records.
