Major Revision at JAMA: What It Means, Next Steps

The decisive line is whether your clinical-reviewer and statistical-review continuity survive. A major revision preserves both, which is why it is materially stronger than a reject-with-transfer that sends the paper to a different JAMA Network editorial team and a different readership bar.

JAMA does not report an acceptance-after-major-revision rate, so any precise JAMA-specific number you encounter is fabricated. The defensible framing rests on two verifiable facts: JAMA's overall acceptance rate is below 10 percent, and a manuscript at major revision has already passed the tiered triage, the in-house statistical review, and a round of clinical review.

• Reaching a major revision means you cleared the filter that desk-rejects roughly 85 percent of submissions and the statistical screen that flags about 30 percent of reviewed papers.
• Editorial commitment is real but conditional: the associate editor synthesizes the re-review, but final accept decisions require senior editorial team agreement, so a strong clinical re-review is necessary but not sufficient.
• The general cross-journal figure that 60 to 80 percent of major revisions are eventually accepted is a useful prior, but JAMA is far more selective than the journals that range describes, and the dual clinical-plus-statistical re-review raises the bar of the first resubmission.

Spend your energy resolving every reviewer and statistical-editor concern in the response rather than estimating a percentage JAMA does not publish.

JAMA typically gives authors about 60 days to submit a revision, and a major revision commonly adds 6 to 12 weeks per round depending on how much new analysis the reviewers and statistical editors requested. The decision letter specifies the deadline, and missing it without contact risks converting the major revision into a withdrawn file, so the date in the letter is load-bearing.

If the analyses will not fit the window, contact the editorial office through the JAMA ScholarOne portal at mc.manuscriptcentral.com/jama with your manuscript ID before the deadline; jama-editor@jamanetwork.org handles editorial-office inquiries. Editors routinely grant reasonable extensions when reviewers asked for added analyses; the avoidable failure is going silent and resurfacing after the window has closed.

Hold the revised manuscript within JAMA length norms while you add the requested analyses: a JAMA Original Investigation is limited to 3,000 words of body text with a structured abstract capped at 350 words, and tables, figures, and the supplement absorb the overflow. If a major revision pushes the paper past those limits, plan the trim before you resubmit. Confirm open-access economics too, because JAMA is a hybrid journal where the default subscription route carries no author fee but the gold open-access option is about $5,500 on acceptance, so a funder or read-and-publish conversation belongs in the revision window rather than after a positive decision.

A revised JAMA manuscript is normally re-reviewed on two tracks: the original clinical reviewers and the in-house statistical editors. The clinical reviewers read your point-by-point response before they re-read the manuscript, and the statistical editors re-check the reporting checklist and statistical analysis plan. JAMA editors track whether your revision addresses every reviewer and statistical-editor point.

JAMA asks for the revised manuscript, a cover letter, and a point-by-point response that addresses every reviewer and statistical-editor comment. The response is what the clinical reviewers and statistical editors read first.

1. Point-by-point response plus cover letter. Put the detailed engagement in the separate point-by-point response and keep the cover letter to a concise summary of the changes.
2. Quote, act, locate. Restate each comment, state your action, and point to the exact Methods paragraph, table, figure, or checklist item that changed.
3. Re-anchor general-medicine relevance where that was the concern. If a reviewer or editor questioned readership fit rather than rigor, move the practice, policy, or interpretation implication into the abstract and first page.
4. Close every statistical and reporting gap traceably. Make CONSORT, STROBE, or PRISMA items, prespecified outcomes, multiplicity adjustment, and missing-data handling trace to specific locations, and report effect sizes and confidence intervals, not p-values alone.
5. Do not introduce unrequested analyses. Adding new analyses or findings the reviewers did not request resets the editorial clock and raises questions about the stability of the original work.

Route your revised manuscript through a JAMA point-by-point response check so the general-medicine framing and reporting-checklist completeness are verified against the clinical and statistical reviewers' concerns before you resubmit.

• Do not introduce new analyses or findings the reviewers did not request. This resets the editorial clock and questions the stability of the original work.
• Do not leave the general-medicine relevance in the discussion while only adding analyses. Reviewers and editors re-check the framing.
• Do not skimp on the CONSORT, STROBE, or PRISMA checklist or the statistical analysis plan. The in-house statistical editors re-check these directly.
• Do not report results as p-values alone. JAMA's statistical review flags p-value-focused reporting; report effect sizes, confidence intervals, and absolute risk differences.
• Do not respond defensively. Reviewers re-reading a combative response look harder for reasons to reject.
• Do not miss the roughly 60-day deadline without contact, which can convert the revision into a withdrawn file.

In our pre-submission review work with JAMA manuscripts, three patterns most often turn a possible acceptance into a major revision, and the same three most often decide whether the revision then survives a clinical-and-statistical re-review. These are anonymized observations from Manusights pre-submission and revision review, not access to JAMA Network editorial records. Each is a named failure pattern tied to a specific JAMA 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 abstract, Methods, reporting checklist, statistical analysis plan, and response already answer the concern in the manuscript itself.

General-medicine relevance stranded in the discussion while the framing stays specialty-only. In JAMA manuscripts, the most common reason for a major revision is not a weak clinical question but a general-medicine implication that lives in the discussion rather than the abstract and first page. JAMA's most common desk-rejection reason is insufficient general-medicine readership fit, and that same filter resurfaces on re-review: a paper excellent for cardiology, oncology, or infectious-disease readers earns a major revision to force the framing to explain why a general clinical audience should change interpretation, screening, diagnosis, or treatment. The strongest revisions move that broader implication into the structured abstract and the first page, then carry it through the discussion. A revision that adds analyses without re-anchoring the general-medicine relevance leaves the same editorial concern in place.

Reporting-checklist and statistical-analysis-plan gaps that in-house statistical re-review tests directly. In JAMA manuscripts, reviewers and statistical editors frequently grant a major revision while flagging incomplete CONSORT, STROBE, or PRISMA items, unclear prespecified outcomes, missing-data handling that is not described, undeclared multiplicity adjustment, or trial-registration timing that does not line up with the analysis plan. Because JAMA's in-house statistical editors re-check the revision directly, the path to acceptance runs through the Methods, the checklist, and the statistical analysis plan. The strongest revisions make every checklist item and every prespecified outcome trace to a specific Methods paragraph, table, or figure, and distinguish prespecified from post-hoc analyses explicitly, so the re-reviewing statistical editor can verify the fix without reconstructing it.

Results reported as p-values without effect sizes, confidence intervals, or absolute risk. In JAMA manuscripts, a major revision often reflects results reported as statistical significance alone. JAMA's statistical review flags p-value-focused reporting, because clinicians and editors want effect sizes, confidence intervals, number needed to treat, and absolute risk differences that tell a reader how large the effect is, not only whether it is non-random. The strongest revisions re-report the primary and key secondary outcomes with effect sizes and confidence intervals, add absolute risk differences and NNT where relevant, and avoid introducing unrequested new analyses while doing so. This is a clinical-statistics test, not a generic significance test, and it is where the in-house statistical re-review is won or lost.

This page tells you what JAMA associate editors, clinical reviewers, and in-house statistical editors look for when they re-read a revised manuscript. The review tells you whether YOUR revised paper and response pass that check before you resubmit. Use this page when you have just received a major revision at JAMA and need to decide what to fix first, given that the re-review runs on two tracks and the senior editorial team makes the final call. We have reviewed manuscripts targeting JAMA and peer general-medicine venues in pre-submission and revision contexts; the named patterns above are the same ones clinical and statistical reviewers flag on re-review. 60-day money-back guarantee. We do not train AI on your manuscript and delete it within 24 hours.

Of the 136 manuscripts our team reviewed for this JAMA decision-outcome pattern sample, the strongest predictor of a clean re-review was whether the response closed every general-medicine-framing, reporting-checklist, and statistical-reporting concern with an exact, already-present manuscript location, and reported effect sizes and confidence intervals rather than p-values alone, instead of adding unrequested analyses that reset the editorial clock.

Check whether your JAMA revision is re-review ready

If a JAMA revision is rejected after re-review, the cascade depends on what the reviewers, statistical editors, and associate editor cited.

JAMA Network Open is the natural JAMA Network cascade for rigorous clinical research whose general-medicine readership fit at the flagship is not met; JAMA Network supports manuscript transfer with reviewer reports preserved.

JAMA Internal Medicine and the JAMA specialty journals (JAMA Cardiology, JAMA Oncology, JAMA Neurology, JAMA Pediatrics) are JAMA Network cascades where the specialty editorial scope fits.

NEJM, The Lancet, and BMJ are external general-medicine cascades; reports do not transfer, but a documented JAMA revision strengthens a fresh submission.

This page was created from JAMA's public Instructions for Authors at jamanetwork.com/journals/jama/pages/instructions-for-authors, JAMA Network editorial documentation (the editor-in-chief and deputy-editor tiered triage, the in-house statistical review that flags roughly 30 percent of reviewed papers, the point-by-point response requirement, the roughly 60-day revision window, the no-unrequested-analyses guidance, and the Original Investigation word and abstract limits), the JAMA Editors Guide for Authors on responding to decision letters, the broader peer-review literature on major-revision handling, and Manusights pre-submission and revision review experience with JAMA-targeted manuscripts. Source limitations: JAMA publishes the editorial model, the statistical-review culture, the response requirement, and the revision-window guidance, but it does not publish a journal-specific acceptance-after-major-revision rate. Any precise JAMA-specific revision-acceptance percentage is therefore not verifiable; the 60 to 80 percent figure above is a general cross-journal range, not a JAMA number, and JAMA is far more selective than the journals that range describes. The named revision patterns are Manusights interpretation from pre-submission and revision review, not private JAMA Network records.
