Circulation Response to Reviewers: How to Write a Rebuttal That Wins (2026)

The single thing that makes a Circulation rebuttal different from a generic one is the independent statistical reviewer. After a favorable initial clinical read, Circulation routes most manuscripts to two to three clinical expert reviewers plus a dedicated statistical reviewer. That statistical reviewer is usually the one who turns a "minor revision" into a "major revision," because the requests are concrete and verifiable: additional subgroup analyses, sensitivity analyses with different covariate adjustments, and an explicit statement of which endpoints were pre-specified versus exploratory.

This is why a Circulation rebuttal cannot be a tone exercise. The clinical reviewers may ask you to soften a claim; the statistical reviewer asks you to produce a number. Your response to the statistical block has to show the analysis actually ran and report what it found, even when the answer is inconvenient.

The second cultural fact: AHA journals enforce a single, explicit response format. Circulation's revised-manuscript instructions ask authors to include a detailed response to each referee and editor comment, providing each comment verbatim in bold followed by your response and giving the exact page, paragraph, and line number(s) where each revision was made. This is not a style preference. A handling editor scanning a 12-page rebuttal uses those page and line numbers to spot-check that the change exists. No location, no credit.

The third fact is the clinical-significance bar that never goes away during revision. The handling editor read your Clinical Perspective box and Novelty and Significance statement at desk stage and let the paper through on a practice-change promise. The revision has to keep that promise. If a reviewer-requested sensitivity analysis shrinks your effect size, you cannot leave the Clinical Perspective box claiming the original magnitude. Editors re-read it on revision, and a perspective box that the revised data no longer support is a fast path to rejection on revision.

State the exact page, paragraph, and line number for every change you reference, in the very first response and every one after it. This is the single most enforced and most ignored rule in the AHA portfolio. Circulation's instructions are explicit that authors must give the exact page number(s), paragraph(s), and line number(s) for each revision, and if you insert important new sentences or sections, you should reproduce them in the response letter and clearly indicate any deletions.

The reason this matters more at Circulation than at many journals: the handling editor and statistical reviewer are checking your arithmetic, not just your prose. When you write "we added a sensitivity analysis," the statistical reviewer wants to land on the exact table and read the new estimate. "We have updated the manuscript" forces them to search, and a reviewer who has to search assumes the change is thinner than claimed. Number every change before you do anything else.

The pattern: never push back without a number, and never let a disagreement with the statistical reviewer sit unresolved. Defensive tone on a cosmetic suggestion costs you a revision round. Defensive tone on a statistical request costs you the paper.

Reviewers and the handling editor read dozens of these letters. Make yours scannable. Put each reviewer comment in bold (Circulation's instructions ask for verbatim-in-bold), and set your response in plain regular text directly beneath it. Many authors add a light gray text box or an indent for the reviewer comment and leave the response flush left, so the eye can distinguish reviewer voice from author voice at a glance.

Do not run the reviewer's words and your reply together in one font and one paragraph; that is the layout editors most often complain about, because it hides whether you actually answered the question.

In our pre-submission review work with Circulation submissions, the manuscripts that survive the revision round and the ones that draw a rejection on revision split along a small set of patterns. Most of the rejection-on-revision cases we see trace to one of the five issues below, not to tone or formatting.

To write this guide we reviewed Circulation's revised-manuscript instructions and the AHA statistical-reporting special report, then mapped them against the editorial-culture patterns our reviewer network accumulates across Circulation-targeted manuscripts. Each pattern below is testable against your own draft response before you upload it.

The statistical-reviewer block is answered last and thinnest. In our analysis of Circulation revision rounds, the most consistent predictor of a second revision is a response document where the clinical reviewers get detailed, numbered replies and the statistical reviewer's request for a sensitivity analysis or pre-specified-versus-exploratory clarification gets a one-line "we have clarified this." Because Circulation routes most papers to an independent statistical reviewer, that block is the one the editor weighs hardest.

This is the specific rejection pattern we move to the front of every rebuttal we review, insisting the new effect size appears in the response letter, not only in a buried supplementary table.

The Clinical Perspective box drifts out of sync with the revised numbers. Manuscripts coming through our pre-submission review pipeline for Circulation routinely keep the original Clinical Perspective box unchanged after a reviewer-requested covariate adjustment shrinks the headline estimate. Editors consistently re-read that box on revision, and a "What Are the Clinical Implications?" bullet that the revised statistical analysis no longer supports is a defamation-of-your-own-data problem. In practice we flag every Clinical Perspective bullet whose magnitude depends on a number a reviewer asked you to re-run.

Promised analyses that the data cannot actually deliver. A pattern we see repeatedly in Circulation rebuttals is an author agreeing to a subgroup analysis the cohort is too small to support, then producing an underpowered result that undercuts the paper.

The better move, which we coach in pre-submission review, is to run the analysis, report the wide confidence interval honestly, and state in the response why the pre-specified primary endpoint remains the basis for the conclusion. Editors trust the rebuttal that admits a limitation more than the one that manufactures a thin subgroup win.

Reporting-checklist items left as "see Methods." Across our Circulation reviews, revised submissions still arrive with a CONSORT or STROBE checklist where half the items point vaguely to the Methods section. When a reviewer asked for trial-registration detail or randomization specifics, the revised checklist has to carry the exact page and line, the same way the response letter does. A checklist that says "see Methods" for a flagged item reads as the change not having been made.

The references in the revised manuscript were never re-checked. Because Circulation revisions often add citations to recent literature the reviewer named, the revised reference list is where a retracted or mislabeled paper slips in. We re-verify every added DOI in a revised Circulation manuscript before resubmission; a single bad citation in a flagship resubmission undoes the credibility the rest of the rebuttal earned.

These five patterns are why a rebuttal that looks complete can still fail. Check your Circulation revised-manuscript readiness before you submit the revision, and the same scan that catches a missing page-and-line citation will flag a Clinical Perspective box that no longer matches your revised analysis. You can also start a manuscript and rebuttal scan from scratch.

Rejection on revision is the honest risk this guide exists to name. A major revision is an invitation, not an acceptance, and at Circulation the second-look bar is set by the same statistical and clinical-significance standards as the first.

Most rejection-on-revision outcomes we see trace to one of three things: a reviewer-requested sensitivity analysis that weakened the primary effect and a rebuttal that tried to bury it, a Clinical Perspective box that still overclaims practice impact the revised data do not support, or new analyses promised in the response that the authors could not actually run.

Roughly speaking, the majority of rejection-on-revision cases we review at Circulation are not about tone or formatting; they are about a number that moved. If the requested analysis makes your headline finding weaker, the winning move is to report it, recalibrate the Clinical Perspective box to the smaller effect, and argue that the recalibrated claim is still clinically meaningful. The losing move is to leave the abstract and perspective box claiming the original magnitude while the supplementary table tells a different story. Editors and statistical reviewers read both.

If the decision is a true rejection rather than a revise, do not send a rebuttal as if it were an appeal. A response-to-reviewers letter answers a revise decision. An appeal is a separate, rarer instrument addressed to the editor, and it should only argue a clear factual error in the review, not relitigate a judgment call about clinical significance.

The 60-day window is firm. If the revision is not received in time, Circulation may treat the manuscript as withdrawn, and a later resubmission is handled as a new submission with a new manuscript number, which means a fresh desk-review gamble. If the new analyses will take longer, request an extension early rather than missing the deadline silently.
