Reviewers' Comments:

Reviewer's Responses to Questions

Key Review Criteria Required for Acceptance?

As you describe the new analyses required for acceptance, please consider the following:

Methods

-Are the objectives of the study clearly articulated with a clear testable hypothesis stated?

-Is the study design appropriate to address the stated objectives?

-Is the population clearly described and appropriate for the hypothesis being tested?

-Is the sample size sufficient to ensure adequate power to address the hypothesis being tested?

-Were correct statistical analysis used to support conclusions?

-Are there concerns about ethical or regulatory requirements being met?

Reviewer #1: To get more reliable data, suggestion to expand the study duration for 5 years

How other differential diagnosis of mycetoma e.g., malignancy and infections were ruled out?

What were the process for sending diagnostic tests? Does histopathology and culture of the amputed specimens were done to confirm the diagnosis?

Mention the duration of medical options as a variable in method?

Explain the severity impairment criteria in methods, how it was classified as sever, Moderate and mild.

Specify in the methods what were the clinical factors for limb loss? e.g., Bone involvement, massive and advance lesion, failed medical treatment, severe superimposed bacterial infections, patient disability, recurrence after surgery.

**********

Results

-Does the analysis presented match the analysis plan?

-Are the results clearly and completely presented?

-Are the figures (Tables, Images) of sufficient quality for clarity?

Reviewer #1: No need for figure 2.

What were the pathogens that were positive in microbiology culture?

Elaborate on histopathological findings, e.g., involvement of bones and tissue reactions

Multivariate logistic regression - "merchant occupation was the only factor significantly associated with delayed care -seeking" This statement is contradictory to the results.

One of the objectives is to document early post-operative outcomes and complication, however in result no descriptions were available.

**********

Conclusions

-Are the conclusions supported by the data presented?

-Are the limitations of analysis clearly described?

-Do the authors discuss how these data can be helpful to advance our understanding of the topic under study?

-Is public health relevance addressed?

Reviewer #1: Conclusion is appropriate, however, i suggest making the discussion more policy relevant that could help the Ethiopian ministry in policy development

**********

Editorial and Data Presentation Modifications?

Use this section for editorial suggestions as well as relatively minor modifications of existing data that would enhance clarity. If the only modifications needed are minor and/or editorial, you may wish to recommend “Minor Revision” or “Accept”.

Reviewer #1: this paper will help in getting data from other regions of Ethiopia

**********

Summary and General Comments

Use this section to provide overall comments, discuss strengths/weaknesses of the study, novelty, significance, general execution and scholarship. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. If requesting major revision, please articulate the new experiments that are needed.

Reviewer #1: overall, this paper could help in developing any policy by getting the baseline data from different regions of Ethiopia. Improvement in clinical detail in the method sections would improve the quality of the paper.

**********

PLOS authors have the option to publish the peer review history of their article (what does this mean?). If published, this will include your full peer review and any attached files.

If you choose “no”, your identity will remain anonymous but your review may still be made public.

Do you want your identity to be public for this peer review? For information about this choice, including consent withdrawal, please see our Privacy Policy.

Figure resubmission:

While revising your submission, we strongly recommend that you use PLOS’s NAAS tool (https://ngplosjournals.pagemajik.ai/artanalysis) to test your figure files. NAAS can convert your figure files to the TIFF file type and meet basic requirements (such as print size, resolution), or provide you with a report on issues that do not meet our requirements and that NAAS cannot fix.

After uploading your figures to PLOS’s NAAS tool - https://ngplosjournals.pagemajik.ai/artanalysis, NAAS will process the files provided and display the results in the "Uploaded Files" section of the page as the processing is complete. If the uploaded figures meet our requirements (or NAAS is able to fix the files to meet our requirements), the figure will be marked as "fixed" above. If NAAS is unable to fix the files, a red "failed" label will appear above. When NAAS has confirmed that the figure files meet our requirements, please download the file via the download option, and include these NAAS processed figure files when submitting your revised manuscript.

Reproducibility:

To enhance the reproducibility of your results, we recommend that authors of applicable studies deposit laboratory protocols in protocols.io, where a protocol can be assigned its own identifier (DOI) such that it can be cited independently in the future. Additionally, PLOS ONE offers an option to publish peer-reviewed clinical study protocols.

Additional Editor Comments: Given that the response letter clearly states the study was "restricted to September 2022–August 2025" it is not appropriate to write in the abstract and methods that the study was over the 5 year 2020-2025 period. The authors should revise the manuscript to state the dates studied. It is reasonable to share in the methods that there was an approach for a longer period, but this was not achievable due to the lack of documentation at the center.

NTD should be written out in the abstract. It is appropriately defined in the main component of the document and can be used after that point.

Table 4. Needs clarification. The authors need to clarify what "Ref" and "Res" means as they are not defined under the table. Also, the results of the multivariate regression indicating that the farmers were the only significant factor are not shown in the text- the statistical result is not shown.

Please review for typos like

Table 1 having "House wife" and not the correct "Housewife" as well as Table 4 having "housewife" while the other occupations are all capitalized.

"out patient" should be "outpatient"

"In the project proposal also we aspired to" should be "we also aspired"

"clinical indicatorssuch as imaging findings, extent of bone involvement, and grain characteristics were frequently missing." Needs a space between indicators and such.

"Despite these limitations, the findings have important implications for clinical care. egional health planning, and national policy development in Ethiopia." The period after care should be a comma and the next word regional.  Journal Requirements:

If the reviewer comments include a recommendation to cite specific previously published works, please review and evaluate these publications to determine whether they are relevant and should be cited. There is no requirement to cite these works unless the editor has indicated otherwise.

1) We note that your Fig 1.tif, and Figure1 recurence of Mycetoma following amputation.tif files are duplicated on your submission. Please remove any unnecessary or old files from your revision, and make sure that only those relevant to the current version of the manuscript are included.

2) We have noticed that you have uploaded Supporting Information files, but you have not included a list of legends. Please add a full list of legends for your Supporting Information files after the references list.

Mycetoma as a Major Cause of Limb Amputation in Northeastern Ethiopia: A Facility-Based Retrospective Study

PLOS Neglected Tropical Diseases

Dear Dr. Enbiale,

Although we appreciate your continued interest in publishing in our journal, the resubmission documents are sub-standard and incomplete. For example, there is no point-by-point response to the second submission, figure 4 is missing from the "manuscript" document, typos remain (example: missing period in the conclusions of abstract " poor outcomes Integrating mycetoma "), etc. However, given the value of your work, we will allow for a re-submission, but it is critical that this next version be very carefully reviewed prior to its return to our editorial staff.

Please submit your revised manuscript within by Apr 24 2026 11:59PM.
