The Major Revision Response Letter

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-28

Quick Answer

• Use a numbered response table that maps each reviewer comment to your reply, the change made, and the location in your revised manuscript.
• Address every comment in order, separate technical feasibility from scientific disagreement, and state clearly what you changed and what you did not change.
• A major revision response letter does not guarantee acceptance, and editors may still request additional work after reviewing your responses.

At a Glance

Understanding the Major Revision Decision

A major revision decision means the editor sees publishable potential but requires substantial changes before the manuscript can be considered further. This decision sits between a minor revision and a rejection. The editor typically sends the reviewer reports to you with a cover letter that explains the required scope of work. The reports may contain overlapping concerns, contradictory requests, or suggestions that are not feasible within your resources.

The Committee on Publication Ethics Core Practices describe peer review as a process where journals should have systems to ensure that submitted work is evaluated fairly and that reviewers provide appropriate feedback. Your response letter is the formal record of how you addressed that feedback. It is not a place to argue with the reviewers in an adversarial way. It is a working document that helps the editor decide whether the revised manuscript meets the journal's standards.

The National Library of Medicine Research Methods Resources provide a gateway to authoritative biomedical books and research-method references that can help you verify whether a reviewer's methodological concern is valid. When a reviewer questions your study design, statistical approach, or reporting completeness, you can consult these references to determine whether the concern reflects a genuine deficiency or a misunderstanding of your methods.

The EQUATOR Network maintains a collection of reporting guidelines for different study types. If a reviewer asks you to follow a specific reporting guideline, or if you realize your manuscript does not follow the relevant guideline for your study design, the EQUATOR Network is the place to identify the correct checklist and the published explanation for each item.

Core Principles of a Response Letter

Respond to Every Comment

The most important rule is that no comment goes unanswered. Reviewers and editors notice when a comment is skipped. Even a brief reply that says you agree and have made the change is better than silence. If you disagree with a comment, you still need to respond with your reasoning and evidence.

Number every comment so that you and the editor can track the correspondence. Use the reviewer's own numbering system when one exists. If the reviewer did not number their comments, create your own numbering and quote the comment in full or in a shortened form that preserves its meaning.

Separate Agreement from Disagreement

For each comment, decide whether you agree, partially agree, or disagree. Your response should reflect that decision clearly. When you agree, state what you changed and where. When you partially agree, explain which part you accepted and which part you did not, then describe what you did. When you disagree, provide your reasoning and cite evidence from your data or from authoritative sources.

The Committee on Publication Ethics Core Practices emphasize that journals should have clear policies on peer review and that editors should handle submissions in a fair and unbiased manner. Your response letter should mirror that fairness by treating each comment on its merits instead of defending your original manuscript reflexively.

Show the Change, beyond the Intention

Reviewers want to see that the manuscript itself changed, beyond that you intend to change it. For each accepted comment, state the specific section, paragraph, or line where the change appears. Quote the revised sentence when the change is substantive. This saves the editor and reviewers from hunting through the manuscript to verify your claims.

The National Library of Medicine Research Methods Resources can help you determine whether a requested change is methodologically sound. If a reviewer asks for a sensitivity analysis, a subgroup analysis, or a different statistical test, consult these references to understand the purpose and limitations of the requested approach before you commit to it.

Building the Response Letter Structure

The Cover Letter to the Editor

The response letter begins with a brief cover section addressed to the editor. This section should state the manuscript title, the manuscript number, and the date. It should thank the editor and reviewers for their time and effort. It should then provide a short summary of the major changes you made in response to the revision request.

The cover section should not repeat the full point-by-point responses. It is a high-level orientation that helps the editor understand the scope of your revision before reading the detailed responses.

The Summary of Changes

After the cover section, include a bulleted or numbered summary of the major changes. This summary should list the most significant alterations to the manuscript, such as new analyses, added sections, reorganized content, or corrected reporting. The summary gives the editor a quick way to assess whether the revision addresses the main concerns.

The EQUATOR Network reporting guidelines can help you identify what needs to change in your manuscript when a reviewer asks for more transparent reporting. If the reviewer requests a flow diagram, a completed checklist, or a specific reporting structure, the relevant guideline will tell you exactly what to include.

The Point-by-Point Response Table

The core of the response letter is the point-by-point table. This table has columns for the reviewer comment, your response, and the location of the change in the revised manuscript. Some authors add a fourth column for the exact revised text.

The table format helps the editor and reviewers navigate the letter quickly. It also forces you to address each comment individually instead of writing a narrative that may skip points.

The Feasibility Explanation

Some reviewer requests are not feasible. You may not have the resources to run a new experiment, the data may no longer be available, or the requested analysis may not be appropriate for your study design. In these cases, you must explain why the request cannot be fulfilled and what you did instead.

A feasibility explanation should state the specific obstacle, such as a lack of funding, the unavailability of samples, or a time constraint. It should then describe any partial action you took, such as adding a limitation paragraph or performing a related analysis that addresses the spirit of the request. The editor can then judge whether your explanation is reasonable.

The National Institutes of Health Grants and Funding website describes the expectations for research conduct and reporting in the context of NIH-funded work. If your study was funded by NIH, your response letter should be consistent with the reporting and transparency expectations that apply to NIH-supported research.

Writing the Point-by-Point Responses

Quote the Comment First

Start each response by quoting the reviewer's comment. Use the reviewer's own words so that the editor can match your response to the original concern. If the comment is long, quote the key sentence or phrase and summarize the rest.

State Your Interpretation

After quoting the comment, state how you understood it. This step is important because reviewers sometimes write comments that are ambiguous or that combine multiple concerns. Your interpretation tells the editor what you think the reviewer meant and gives the reviewer a chance to correct you if you misunderstood.

Describe Your Action

Describe what you did in response to the comment. Be specific about the change you made. If you added a sentence, quote it. If you reanalyzed data, describe the method and the result. If you reorganized a section, explain the new structure.

Provide the Location

Give the exact location of the change in the revised manuscript. Use section numbers, paragraph numbers, or page numbers when the journal uses them. If the journal uses line numbers, include those as well. The location helps the editor and reviewers verify your work without reading the entire manuscript.

Explain Disagreements with Evidence

When you disagree with a comment, explain why. Your explanation should be grounded in your data, your study design, or authoritative references. The National Library of Medicine Research Methods Resources can provide methodological support for your position. The EQUATOR Network can provide reporting guideline support. The Committee on Publication Ethics Core Practices can provide ethical context for publication-related concerns.

Do not simply say that you disagree. Show the editor why your original approach was appropriate or why the reviewer's requested change would introduce a different problem.

Handling Different Types of Reviewer Comments

Requests for Additional Experiments

A reviewer may ask for an experiment that you cannot perform. Before responding, consider whether the experiment is truly necessary for the manuscript's conclusions or whether it is a nice-to-have addition. If the experiment is necessary, you may need to acknowledge that the manuscript cannot make certain claims without it and revise your conclusions accordingly.

If the experiment is not feasible, explain the specific obstacle and describe what you did instead. You might add a limitation paragraph, perform a related analysis using existing data, or cite published work that addresses the question. The editor will decide whether your alternative is acceptable.

Requests for Additional Analyses

Statistical or data analyses are often feasible even when new experiments are not. If a reviewer asks for a sensitivity analysis, a subgroup analysis, or a different modeling approach, consider whether your data can support it. If the analysis is possible, perform it and report the results. If it is not possible, explain why the data cannot support the requested analysis.

The National Library of Medicine Research Methods Resources can help you understand the purpose and limitations of different analytical approaches. Use these references to determine whether the requested analysis is appropriate for your data structure and study design.

Requests for Reporting Changes

Reviewers often ask for changes that improve reporting transparency. These requests are usually easy to fulfill. The EQUATOR Network provides reporting guidelines for many study types, including randomized trials, observational studies, systematic reviews, and diagnostic accuracy studies. Identify the relevant guideline for your study and follow its checklist.

When you complete a reporting checklist, state in your response that you have done so and provide the checklist as a supplementary file if the journal accepts it. The EQUATOR Network website explains how to select the appropriate guideline and how to use it in your manuscript preparation.

Requests for Language or Clarity Improvements

Some comments ask for clearer writing, better organization, or more accessible language. These comments are subjective but still deserve a response. State that you have revised the relevant sections and describe the nature of the revision. If you used a professional editing service, you can mention that, but you do not need to provide details.

Contradictory Comments from Different Reviewers

Reviewers sometimes make contradictory requests. One reviewer may ask for more detail while another asks for less. One may ask for a specific analysis while another questions its validity. When this happens, you must make a judgment call and explain it to the editor.

State that the reviewers made conflicting requests, explain how you resolved the conflict, and justify your decision. The editor will understand that you cannot satisfy both reviewers simultaneously and will appreciate a reasoned explanation of your choice.

The Response Letter Template

Using the Template Effectively

The template provides the skeleton, but the content of each response determines the quality of your letter. Write each response with the same care you would give to a paragraph in your manuscript. Be precise about what you changed and where. Be honest about what you did not change and why.

The ORCID for Researchers website explains how researchers can maintain a persistent digital identifier that links their research activities and outputs. Including your ORCID iD in your correspondence with the journal helps the editor and reviewers verify your identity and connect your revision to your broader research record.

Records and Measurements

Tracking Your Responses

Create a tracking document before you write the response letter. List every comment from every reviewer and the editor. For each comment, record your planned action, the status of that action, and the location of the change in the revised manuscript. This tracking document prevents you from missing a comment and helps you write the response letter efficiently.

The tracking document can be a simple spreadsheet with columns for the reviewer number, the comment number, the comment text, your planned action, the status, and the manuscript location. Update the status as you complete each action.

Verifying Your Changes

Before you submit the response letter, verify that every change you describe actually exists in the revised manuscript. Read the revised manuscript alongside your response letter and check each location. This verification step catches errors where you described a change that you did not actually make or cited a location that does not match the revised text.

The National Institutes of Health Data Management and Sharing Policy describes expectations for managing and sharing scientific data generated from NIH-funded research. If your manuscript reports NIH-funded research, your revision should be consistent with the data management and sharing expectations that apply to your project.

Common Failure Patterns

The Defensive Response

A defensive response argues with the reviewer without offering any change or reasoned justification. This pattern damages your credibility with the editor. Even when you disagree with a comment, your response should acknowledge the reviewer's perspective, explain your reasoning, and offer whatever change you can make without compromising your scientific integrity.

The Vague Response

A vague response says that you have addressed the comment without specifying what you did or where. The editor cannot verify your claim without reading the entire manuscript. Provide the specific location and quote the revised text so that the editor can confirm your work.

The Incomplete Response

An incomplete response skips some comments or addresses them only partially. This pattern forces the editor to chase you for missing information and may delay the decision. Use your tracking document to ensure that every comment receives a response.

The Overpromising Response

An overpromising response claims that you have made changes that you have not actually made. This pattern is worse than an incomplete response because it misleads the editor. If you cannot make a requested change, explain why instead of claiming that you did.

The Disorganized Response

A disorganized response presents your replies in a narrative format that is difficult to follow. The editor must search through paragraphs to find the response to a specific comment. Use the numbered table format so that each comment and response is easy to locate.

Welfare and Safety Context

Research Integrity and Publication Ethics

The Committee on Publication Ethics Core Practices describe the responsibilities of authors, reviewers, and editors in maintaining the integrity of the scholarly record. Your response letter is part of that integrity framework. It should accurately represent the changes you made and honestly explain the limitations of your work.

The Core Practices cover areas such as authorship, peer review, data access, conflicts of interest, and misconduct. If your revision touches on any of these areas, such as adding an author, disclosing a conflict, or correcting a data error, your response letter should address the issue transparently.

Data Management and Sharing

The National Institutes of Health Data Management and Sharing Policy describes expectations for managing and sharing scientific data. If your study is subject to this policy, your revision may need to include a data availability statement, a data management plan, or a description of how data can be accessed. Your response letter should state what you have done to meet these expectations.

The National Institutes of Health Grants and Funding website provides information about the policies that apply to NIH-funded research. If your project is NIH-funded, review the relevant policies to ensure that your revised manuscript and response letter are consistent with your funding obligations.

Professional Escalation Criteria

When to Contact the Editor

Contact the editor directly if you encounter a situation that you cannot resolve through the normal response process. Examples include a reviewer request that would require unethical conduct, a request that is impossible to fulfill and where your explanation may not be sufficient, or a concern about the peer review process itself.

The Committee on Publication Ethics Core Practices describe the responsibilities of editors in handling submissions and managing peer review. If you believe that the peer review process was unfair or that a reviewer acted inappropriately, you can raise your concern with the editor. The editor has the responsibility to handle your concern fairly.

When to Seek Institutional Support

If your revision involves a dispute about authorship, data ownership, or research misconduct, seek support from your institution before responding to the journal. Your institution may have policies and offices that can help you navigate these situations. The Committee on Publication Ethics Core Practices provide context for how journals handle these issues, but your institution is the appropriate first point of contact for disputes that involve your employment or your research record.

When to Withdraw the Manuscript

Withdrawal is an extreme step that you should consider only when the revision requirements are fundamentally incompatible with your scientific integrity or when the peer review process has become unworkable. Before withdrawing, discuss the situation with your coauthors and your institution. Withdrawal has consequences for your research record and may affect future submissions to the same journal.

Limitations of the Response Letter

The Response Letter Does Not Guarantee Acceptance

A well-written response letter improves your chances, but it does not guarantee that the editor will accept the revised manuscript. The editor may send the manuscript back to the reviewers, may request additional revisions, or may reject the manuscript even after a thorough revision. Your response letter is one part of the revision process, not a guarantee of the outcome.

The Response Letter Cannot Fix Fundamental Problems

If the reviewers identified fundamental problems with your study design, your data, or your conclusions, no response letter can fix those problems. You may need to acknowledge the limitations in your manuscript, revise your conclusions, or in some cases, acknowledge that the study cannot be published as originally conceived.

The Response Letter Requires Honest Representation

Your response letter must accurately represent the changes you made. Misrepresenting your work in a response letter is a form of publication misconduct. The Committee on Publication Ethics Core Practices describe the responsibilities of authors to accurately represent their work and to correct errors when they are identified.

Practical Implementation Steps

Step 1: Read All Comments Carefully

Read the editor's decision letter and all reviewer reports in full before you begin any work. Take notes on each comment and identify the main themes. Some comments will be straightforward requests for changes, while others will require interpretation.

Step 2: Create Your Tracking Document

Create a spreadsheet or document that lists every comment. For each comment, record the reviewer number, the comment number, the comment text, your planned action, and the status. This document will guide your revision work and your response letter.

Step 3: Consult Relevant Guidelines and References

If the reviewers asked for reporting changes, identify the relevant reporting guideline on the EQUATOR Network. If the reviewers raised methodological questions, consult the National Library of Medicine Research Methods Resources. If the reviewers raised ethical or publication policy questions, consult the Committee on Publication Ethics Core Practices.

Step 4: Make the Manuscript Changes

Revise the manuscript to address the comments you have accepted. Track your changes if the journal requires it. Keep a record of every change you make so that you can describe it accurately in your response letter.

Step 5: Write the Response Letter

Write the response letter using the template structure. Address every comment in order. Quote each comment, state your interpretation, describe your action, and provide the location of the change.

Step 6: Verify Your Work

Read the revised manuscript alongside your response letter. Verify that every change you described exists and that every location you cited is correct. Check that you have not missed any comments.

Step 7: Submit the Revision

Submit the revised manuscript, the response letter, and any supplementary files through the journal's submission system. Follow the journal's instructions for the format and naming of files.

Frequently Asked Questions

How long should a major revision response letter be?

The length depends on the number of comments and the complexity of your responses. A response letter for a major revision is often several pages long because it addresses every comment individually. Focus on completeness and clarity instead of a specific page count. A short letter that addresses every comment is better than a long letter that is vague or repetitive.

Should I respond to every single reviewer comment?

Yes. Every comment from every reviewer and the editor should receive a response. Skipping a comment suggests that you did not read the reports carefully or that you are avoiding a difficult issue. Use a tracking document to ensure that no comment is missed.

How do I respond to a reviewer comment I disagree with?

State that you disagree, explain your reasoning, and provide evidence from your data or from authoritative sources. Acknowledge the reviewer's perspective even when you disagree. Offer whatever change you can make without compromising your scientific integrity. The editor will decide whether your explanation is sufficient.

What should I do if a reviewer asks for an experiment I cannot perform?

Explain the specific obstacle that prevents you from performing the experiment. Describe any partial action you took, such as adding a limitation paragraph or performing a related analysis. The editor will judge whether your explanation is reasonable. Do not claim that you performed an experiment that you did not perform.

Should I use tracked changes in my revised manuscript?

Many journals require tracked changes for revised manuscripts so that editors and reviewers can see exactly what changed. Check the journal's instructions for authors. If tracked changes are not required, you may still use them to make your revision easier to verify. Your response letter should state how changes are marked in the revised manuscript.

How do I handle contradictory comments from different reviewers?

State that the reviewers made conflicting requests, explain how you resolved the conflict, and justify your decision. The editor will understand that you cannot satisfy both reviewers simultaneously. Your explanation should show that you considered both perspectives and made a reasoned choice.

Can I submit a response letter without a summary of changes?

You can, but a summary of changes helps the editor understand the scope of your revision quickly. The summary is especially useful when the revision involves many changes or when the changes are substantial. Include a brief summary at the beginning of your response letter even if the journal does not require it.

What should I do if I realize the reviewers found a real error in my work?

Acknowledge the error, correct it in the manuscript, and explain the correction in your response letter. The Committee on Publication Ethics Core Practices describe the responsibility of authors to correct errors in the scholarly record. An honest correction is better than a defensive response that tries to minimize the problem.
