-->3. Have the authors made all data underlying the findings in their manuscript fully available?

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception (please refer to the Data Availability Statement in the manuscript PDF file). The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.-->

Reviewer #1: Yes

Reviewer #2: Yes

Reviewer #3: No

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)-->

Reviewer #1:  This study presents a retrospective cohort analysis investigating the factors predicting major versus minor amputations in 434 patients who underwent amputation due to diabetic foot infection (DFI) over a 10-year period. The topic is clinically important, and given the scarcity of data from Southeast Asia, the study has the potential to contribute meaningfully to the existing literature.However, there are several important issues, particularly within the Methods section, that require clarification.

1. The title is engaging; however, if the term ‘silent epidemic’ is derived from an official health authority, this should be clearly stated in the Introduction. If it reflects the authors’ own interpretation, the phrasing should be softened accordingly.

2. The keywords should be revised to align with appropriate MeSH terminology.

3. The Introduction provides an excessive level of detail, extending into the pathophysiology of diabetes unnecessarily.Please shorten this section so that it focuses primarily on the rationale for the study and the existing gap in the literature.

4. Please state your study aim and hypothesis clearly and separately, without merging the two.

5. More professional and structured subheadings should be used in the Methods section.

6. Please clarify whether the recorded data represent the first amputation for all participants.

7.What is the purpose of reporting the initial and final data access dates? This information does not appear to contribute meaningfully to the Methods section.

8. Similarly, it is unclear why this detailed explanation regarding medical record ownership and regulatory provisions is included. This information does not enhance the scientific clarity of the Methods section and appears unnecessary for the context of ethical approval or data use.

9. In line 118 on page 5, you state that there were no missing data; however, this contradicts the results section, where several variables show substantial missingness.

10. Please clarify whether there were any pregnant women in the dataset and specify how many patients presented with dry foot gangrene. These details are necessary to understand the rationale for the exclusion criteria and the composition of the study cohort.

11.Please specify which clinical guideline was followed in determining the treatment approach (e.g., IDSA, IWGDF, or national/local protocols). If a standardized institutional care pathway or treatment checklist was used, please provide access to or details of this protocol.

12.Information regarding the clinicians’ level of experience, calibration meetings, and the standardization of assessment protocols is not provided.

13.Unfortunately, there are several clinically relevant variables missing that could substantially influence the regression analysis. Given that these parameters are typically available in electronic medical record systems, it is unclear why they were not retrieved. Could the authors clarify the reason for this limitation?

14. The rationale for using a z-test, despite the availability of more appropriate and contemporary statistical methods, should be clarified. In addition, the quality metrics for the logistic regression model need to be reported.

15. The manuscript states that the data preparation, analysis, and visualization code are published online; however, these materials are not accessible. Please provide a functional link or clarify where these resources can be obtained.

16.The Results section contains repeated information and should be streamlined. Please summarise the findings more concisely and refer readers to the relevant tables and any additional figures or graphs that could be incorporated to improve clarity.

17.Could you present the missing data in a more organized and consolidated manner?

Reviewer #2:  1. Recommend a more rigorous English language proofing. Multiple areas need rewording (Line 40/41; Line 51; Line 78)

2. Line 55 - To say "DFI leads to ulceration" is not true. Ulcerations develop and then become infected given patients' increased risk, neuropathy, PVD, deformity, etc.

3. Line 56 - "Diabetic foot ulcers..." This is an opinion and should be rephrased.

4. Materials and Methods: Were x-ray and/or MRI findings not included? Aside from blood work, hospital admissions (at least in the US) always include x-ray +/- MRI, vital signs, CBC, CMP, ESR, CRP.

5. Other patient demographics/historical pieces to consider (I know it's hard to obtain this in a retrospective review): Insulin vs. Non-insulin dependent diabetes; previous amputation?; approximate length of time ulcer has been present before admission

Reviewer #3:  Title:

Nonacademic words (silent epidemic, insight), lack of study design, clarify that the study from single center

Abstract:

Correct the format.

Add the definition of major and minor amputation

Add more details abouts statistical results such as p value

Avoid general terms and nonacademic terms

Conclusion should be more descriptive than interpretative, and should be more concise and precise

Introduction:

Overly long, and a lot of repetition

Have a lot of information about DM, not necessary to the scope of paper, focus on DFI

Lacks of study flow toward aim

Clear the knowledge gap and objective

Method:

No need to mention detailed local administration rules

Lacks of inclusion and exclusion criteria

Lacks of detailed data handling (incomplete data, deaths, conversion from minor to major amputation, recurrent cases, bilateral)

Inconsistent definitions (major and minor amputation according to literature

Peripheral neuropathy and peripheral vascular disease, way of diagnosis??

Statistics?

Ethical approval should be more concise

Results:

the Results should only report findings, without explanation and interpretation

make more concise without addition of literature and background information

Discussion:

Too long, a lot of repetition, need to be concise

Studies put back to back, need to incorporate its implication to study results

Make it more clear

Results should be interpreted and supported with literature

Limitation:

should be addressed, and mentioned after discussion

Conclusion:

should be more concise and highlight the contribution of the study

Revision 3

The authors are deeply grateful to Reviewer 3 for their pertinent comments that helped them improving the article to make it sharper and more concise.

We changed the title to: 'Risk Factors Associated with Diabetic Foot Amputation: A Retrospective Study from a Tertiary Hospital in Central Malaysia'

We removed promotional language in the Abstract (strong, substantial) and shortened it to 180 words.

We shortened the Introduction to 522 words and 13 core references.

We removed the information about the ethical approval from the method as pasted it into the dedicated box in the manuscript submission (assuming it will appear at the bottom of manuscript').

We renamed a section 'Data handling and statistical analysis' that merges the previous sections 'Dataset' and 'Statistical analysis' and provided more information about the data handling procedures (lines 106-114).

We added more information about the diagnosis of peripheral neuropathy and peripheral vascular disease in the 'Study design and procedure' section (lines 75-89).

We cleaned the Results section to include only relevant results and statistical considerations with no interpretation.

We shortened the limitations and added them to the last part of Discussion.

We shortened the Conclusion to 109 words.

Open letter on the publication of peer review reports

PLOS recognizes the benefits of transparency in the peer review process. Therefore, we enable the publication of all of the content of peer review and author responses alongside final, published articles. Reviewers remain anonymous, unless they choose to reveal their names.

We encourage other journals to join us in this initiative. We hope that our action inspires the community, including researchers, research funders, and research institutions, to recognize the benefits of published peer review reports for all parts of the research system.
