A decision letter requesting major revisions is one of the most misread moments in the publication process. Received on a deadline, after months of work, it can feel like a near-rejection. It is closer to the opposite. An invitation to revise, even a major revision, means the editor sees a publishable paper and is telling you what stands between the current draft and acceptance. The evidence bears this out: once a manuscript is invited to revise rather than rejected outright, the probability of eventual acceptance rises sharply. What determines whether you convert that invitation is not the length of the reviewers' comments but the quality of your response to them. For systematic reviews, the response must address a recognizable set of methodological requests. Our response to peer reviewers service builds exactly these responses for evidence syntheses.
This guide sets out the structure of a point-by-point response that editors expect, the professional norms that govern it, how to handle disagreement and conflicting reviewers, and the systematic-review-specific requests, updated searches, PRISMA compliance, GRADE, and risk of bias that most often appear.
Quick Answer:
Respond to major revisions with a point-by-point letter that reproduces every reviewer comment verbatim and answers each one directly beneath it, stating what you changed and citing the exact location of the change. Respond to every comment, even those you disagree with, because editorial bodies, including COPE and ICMJE, expect it. Where you disagree, acknowledge the point and rebut it with evidence rather than ignoring it. For systematic reviews specifically, expect requests to update the search to within months of resubmission, to demonstrate PRISMA 2020 compliance with a reconciled flow diagram, to add or strengthen risk-of-bias assessment and GRADE certainty ratings, and to justify or add protocol registration. A major-revision invitation signals the editor sees publishable work, so a disciplined response usually converts it to acceptance.
What a Major-Revision Decision Actually Means
Journals typically issue one of several decisions after review: reject, major revision, minor revision, or accept, occasionally with intermediate categories such as reject-and-resubmit. Understanding where major revision sits in that hierarchy shapes how you should read it.
Major revision signals that the editor and reviewers have identified substantive concerns, often in the methods, the analysis, or the completeness of the synthesis, that must be resolved before the paper can be accepted, and that resolving them will usually require another round of review. Minor revision signals that the remaining concerns are largely editorial or easily addressed, with a lighter re-check. Neither is a rejection. Both mean the editor considers the work fundamentally publishable, which is the single most important fact to hold onto when the comments run to several pages. The practical implication is that a major-revision decision rewards thoroughness: the editor has already decided the paper has merit. Your task is to demonstrate that every substantive concern has been fully resolved. Our guide on how to write a revise-and-resubmit response that gets accepted covers the general case; this article focuses on what is distinctive for systematic reviews.
Major Versus Minor Revisions, and What Each Requires
The distinction between the two revision categories is not merely administrative, because it tells you how much work the editor expects and how the re-review will proceed.
A major revision usually means the paper returns to one or more of the original reviewers, who will assess whether their concerns were addressed. This raises the stakes of the response letter, because it is read by the people who raised the objections, and a response that dismisses or sidesteps a concern will be visible to the person who raised it. A minor revision more often returns only to the editor, who checks that the smaller points were handled. The response to a major revision, therefore, has to be more complete, more evidenced, and more carefully worded, because its audience is the original critics.
Table 1: Major vs Minor Revisions, and What Each Signals
Dimension | Major Revision | Minor Revision |
|---|---|---|
Nature of concerns | Substantive: methods, analysis, completeness of synthesis | Largely editorial or easily addressed |
Re-review | Usually returns to the original reviewers | Often checked by the editor only |
Response demands | Complete, evidenced, carefully worded for the critics | Concise confirmation of each fix |
What it signals | Editor sees publishable work with resolvable concerns | Paper is close to acceptance |
Is it a rejection? | No | No |
The Structure of a Point-by-Point Response
The point-by-point response letter is the instrument that converts a revision invitation into an acceptance, and its structure is a settled convention that editors expect. Departing from it makes the editor's job harder and signals inexperience.
Open with a brief note to the editor thanking them and the reviewers for their time and stating that you have addressed all comments, with a one or two-sentence summary of the most significant changes. Then address each reviewer in turn, and within each, reproduce every comment verbatim before your response. Do not paraphrase the reviewer's comment or group several together; quoting each in full shows you have understood it and lets the reviewer find their point immediately. Beneath each quoted comment, state your response: whether you agree, what you changed, and, critically, where the change appears, citing the page and line number or quoting the revised text. Distinguish the reviewer's words from yours visually, through a different font color, italics, or a clear label such as "Author response," so the letter is easy to navigate.
Submit the response as a separate document alongside two versions of the manuscript: a clean copy and a tracked-changes copy, so the editor and reviewers can verify each change against your description of it. This format is codified in author guidance from major style bodies, including the American Psychological Association's guidance on responding to reviewers, and it is the form editors are trained to expect. A response that cites exact locations and quotes the revised text is one a reviewer can verify in minutes; a vague response that asserts changes without locating them forces the reviewer to hunt for them and invites a second round of the same objection.
Tone and the Professional Norms That Govern the Response
The norms governing author responses are not merely etiquette; they are expectations of the editorial bodies that define publication ethics. The Committee on Publication Ethics and the ICMJE Recommendations both frame peer review as a constructive professional exchange in which authors are expected to engage with every substantive comment. Ignoring a comment is the one response editors will not accept, because it leaves a raised concern unresolved on the record.
The governing tone is measured and professional, regardless of the tone of the review. Reviewers are occasionally brusque or appear to have misread the paper. The productive response is to extract the legitimate scientific point from the comment and address it with a specific revision, never to mirror any hostility. Where a reviewer has misunderstood something, the charitable reading is usually that the manuscript was not sufficiently clear, and the strongest response both clarifies the text and notes the clarification, so that the next reader will not make the same error. This turns a critical comment into an improvement to the paper, which is precisely what an editor wants to see.
Handling Disagreement and Conflicting Reviewers
Two situations test the response letter, and handling them well is a mark of a capable author.
The first is a genuine disagreement with a reviewer. You are not obliged to make every change a reviewer requests, but you are obliged to respond to every request. Where you disagree, acknowledge the comment, then set out your reasoning with evidence and citations, in a form the editor can adjudicate. A response of the form, " We understand the reviewer's concern. However, the following evidence supports our original approach, which is legitimate and often successful, because the editor makes the final decision, and a well-reasoned rebuttal gives them grounds to side with you. What fails is silent non-compliance: making no change and offering no explanation.
The second is conflicting reviewers, where one reviewer asks for the opposite of another. State the conflict openly to the editor rather than quietly satisfying one and ignoring the other. Choose a defensible direction, explain why, and let the editor arbitrate. A common and effective compromise, where one reviewer wants more detail and another wants less, is to move the disputed material to supplementary files, satisfying the request for completeness while keeping the main text focused. Naming the conflict explicitly protects you because it shows the editor you engaged with both reviewers rather than neglecting one.
The Systematic-Review-Specific Requests
Beyond the general norms, systematic reviews attract a recognizable set of methodological requests at major revision, and anticipating them lets you resolve them fully rather than triggering a further round.
The most common is a request to update the search. Because a systematic review must reflect the current evidence, reviewers frequently ask that the search be re-run so that it is current to within a short window of resubmission. There is no single universal rule on how recent the search must be, and expectations vary by journal. Still, a search that is current to within roughly six to twelve months of resubmission is a common expectation, and a search more than a year or two old at resubmission will often be challenged. Updating a search and screening the new records is substantial work, and it is one reason the search strategy is a distinct service.
The second is a request to demonstrate PRISMA 2020 compliance. Reviewers commonly ask for the completed 27-item PRISMA 2020 checklist and a flow diagram that reconciles exactly with the numbers reported in the text, since a flow diagram whose figures do not add up is an immediate flag. The third is a request to add or strengthen the risk-of-bias assessment, using a design-appropriate tool, and to carry it through into the interpretation. The fourth is a request to add GRADE certainty-of-evidence ratings, or to defend the ratings already presented; our guide on GRADE certainty ratings covers how to respond to a downgrade specifically, and our statistical analysis service handles the statistical elements of these requests. The fifth is a request to register the protocol, or to justify its absence and address the resulting limitation. Recognizing these five in advance means you can often satisfy them decisively in a single revision.
Table 2: The Five Systematic-Review-Specific Requests to Anticipate
Request | What Reviewers Expect |
|---|---|
Update the search | Search current to within roughly 6 to 12 months of resubmission (journal-dependent; no universal rule) |
PRISMA 2020 compliance | Completed 27-item checklist and a flow diagram that reconciles with the text |
Risk-of-bias assessment | Design-appropriate tool, carried through into the interpretation |
GRADE certainty ratings | Certainty of evidence rated per outcome, or existing ratings defended |
Protocol registration | Registered protocol cited, or its absence justified as a limitation |
Why Systematic Reviews Are Sent for Major Revision
Understanding the recurring reasons systematic reviews are sent back, rather than accepted or rejected, helps you pre-empt them and read the reviewers' comments in context. Reviews are commonly sent for major revision because the rationale for the review is weakly motivated, because the methodology is incompletely reported, because the PRISMA checklist or a reproducible search strategy is missing, because risk-of-bias or GRADE assessment is absent. After all, the search is outdated, or because the review's scope does not match the journal. Each of these is a resolvable concern rather than a fatal one, which is why they draw a revision request rather than a rejection. Our analysis of why systematic reviews get rejected covers the more serious versions of these problems, and our guide on how to get your systematic review published sets the revision stage in the wider publication process.

What a Single Point-by-Point Exchange Looks Like
Because the abstract structure is easier to describe than to execute, it helps to see the anatomy of one exchange. Consider a reviewer's comment on a systematic review of a nursing intervention.
The reviewer writes that the search appears to have been limited to two databases and that this may have missed relevant trials indexed elsewhere. A weak response asserts, without detail, that the search was adequate. A strong response reproduces the comment in full, then answers it concretely: it agrees that two databases is a limitation, states that the search has been extended to a third and a fourth database and a trial registry, reports how many additional records this returned and how many new studies were included, and cites the exact section and lines of the revised methods where the expanded search is described, along with the updated PRISMA flow diagram figures. The reviewer can verify every element of that response in the tracked-changes manuscript in under a minute, and the concern is closed.
Now consider a comment that the authors disagree with. A reviewer asks the authors to pool two subgroups that the authors deliberately kept separate because of clinical heterogeneity. The authors do not make the change, but they do not ignore the request. They acknowledge the comment, explain that the two subgroups differ in a way, for example, in the dose or the population, that makes a pooled estimate clinically uninterpretable, cite the methodological basis for keeping them separate, and note that they have added a sentence to the methods making the rationale explicit for future readers. The editor can now adjudicate on a clear, evidence-based disagreement. This is the difference between a rebuttal and non-compliance: the change was declined, but the request was fully answered, and the clarification improved the manuscript that the objection prompted. Constructing responses of this quality across an entire decision letter is the substance of our response to peer reviewers service, which pairs the methodological work with the writing.
Sequencing the Revision Work
The order in which you tackle a major revision matters because some changes cascade into others. Begin by reading all reviewer comments together and grouping them: the straightforward fixes, the substantive but manageable requests, and the few that threaten the paper's acceptance if mishandled. Resolve the threatening ones first, because their resolution often reshapes the manuscript in ways that affect the smaller points. For a systematic review, an updated search is the first substantive task, because new included studies change the synthesis, the risk-of-bias table, the GRADE ratings, the flow diagram, and potentially the conclusions. Running the analyses before drafting the response prevents the common error of writing responses that the eventual data then contradict. Once the substantive work is complete and the manuscript is revised, draft the point-by-point letter against the final version, so that every location you cite is accurate. Then verify each response against the tracked-changes manuscript before submitting, confirming that every promised change is actually present at the location you cited. Where the revision requires substantial rewriting of the methods or synthesis to accommodate new studies, our systematic review writing service can rebuild those sections to match the updated analyses.
Frequently Asked Questions
Is a major revision decision close to a rejection?
No. A major-revision decision means the editor considers the paper fundamentally publishable and is telling you what must be resolved before acceptance. Once a manuscript is invited to revise rather than rejected, the probability of eventual acceptance rises substantially. The comments may be extensive, but the decision itself is a signal of merit, not a soft rejection.
Do I have to make every change a reviewer requests?
No, but you must respond to every comment. You may decline a requested change if you can justify your position by acknowledging the comment and setting out your reasoning with evidence and citations for the editor to adjudicate. What editorial bodies do not accept is ignoring a comment or making no change without explanation. A well-reasoned rebuttal is legitimate; silent non-compliance is not.
How recent does my search need to be when I resubmit?
There is no single universal rule, and expectations vary by journal, but reviewers commonly expect the search to be current to within roughly six to twelve months of resubmission. A search more than a year or two old at resubmission will often be challenged. Because updating the search can change your included studies and therefore your synthesis, plan to re-run it early in the revision.
How do I handle two reviewers who want opposite things?
State the conflict openly to the editor rather than satisfying one and ignoring the other. Choose a defensible direction, explain your reasoning, and let the editor arbitrate. Where one reviewer wants more detail, and another wants less, a common solution is to move the disputed material to supplementary files, which satisfies the request for completeness while keeping the main text focused.
What is the correct structure for a point-by-point response?
Open by thanking the editor and reviewers and summarizing the main changes. Then, for each reviewer, reproduce every comment verbatim and respond directly beneath it, stating what you changed and citing the exact page and line or quoting the revised text. Distinguish the reviewer's words from yours visually, and submit the letter alongside clean and tracked-changes versions of the manuscript.
What systematic-review-specific changes are reviewers most likely to request?
The most common are updating the search to a recent window, demonstrating PRISMA 2020 compliance with a reconciled flow diagram, adding or strengthening the risk-of-bias assessment and carrying it into the interpretation, adding or defending GRADE certainty ratings, and registering the protocol or justifying its absence. Anticipating these five lets you resolve them in a single revision rather than triggering another round.
Should I respond to reviewer comments before or after revising the manuscript?
Revise the manuscript first, then draft the response against the final version, so every location you cite is accurate. For a systematic review, complete the substantive work, especially an updated search and its downstream effects on the synthesis, before writing responses, because the eventual data can contradict responses written before the analyses.

Converting the Invitation
A major revision decision is the editor holding the door open. The authors who walk through it are the ones who treat every comment as a specific, answerable request: reproduced in full, addressed with a located change, and rebutted with evidence where they disagree. Handle the systematic-review-specific requests decisively, update the search before everything else, reconcile the flow diagram, and verify each promised change is present before you resubmit. Done that way, the page of comments becomes the last obstacle rather than a new one.
