Additional Editor Comments:

Dear Authour

Thank you for submitting the paper titled: Perception and coping mechanisms among diabetes mellitus patients at the University College Hospital, Ibadan, Nigeria, during the COVID-19 pandemic to Plos one Journal

We are pleased to let you know that your manuscript has now passed through the review stage and is ready for major revision. Many manuscripts require a round of revisions, so this is a normal but important stage of the editorial process. The manuscript has the potentialto be published but may not be accepted if the authors do not address substantive issues

REVIEWER 1:

I reviewed an article entitled “Perception and coping mechanisms among diabetes mellitus patients at the University College Hospital, Ibadan, Nigeria, during the COVID-19 pandemic”. It was interesting to read. A few changes were required to improve the general structure of the work.

The abstract is relatively long and may exceed the maximum number of words permitted. It might be enhanced by condensing the introductory and conclusion sections. The results should clearly state the themes and subthemes that emerged from the investigation in the first place and please provide a brief explanation for each subtheme.

Overall, you have justified your research nicely in the introduction. However, the method needs to be modified so that it answers the research's objectives and title.

The study's title clearly states that the research mostly featured Dm patients, and you are interested in learning about their perceptions and coping mechanisms while dealing with the management of DM and pandemic covid-19. However, you did include two professional healthcare workers as respondents in your method. Please explain why they were added.

How did you select participants for the qualitative study? Please give a citation for your response.

How did you assure the respondents' diversity?

Please omit the word “only” in your description of study criteria. Restructure your statement to make the grammar more readable.Restructure your statement to make the grammar more readable.

Who developed the questions for data collection? How do the questions appear? Please give an example of the questions that were asked. Who verifies each of the questions before they are used? How many times did the verification procedure occur?

What if the appointment was cancelled or the participant was unable to keep to the schedule because the interview was held in a hospital setting? How many times did the interview take place in total? How did you conduct the interview? Did you use a local language or English? Please provide specifics.

In terms of data analysis, please describe in detail the thematic process that you used in the study. Who checked the interview verbatim and was it shown to the respondents before it was processed further?

The four requirements to grow trustworthiness and establish rigors were credibility (internal validity), transferability (external validity/generalizability), dependability (reliability), and confirmability (objectivity), how did you confirm all of these aspects?

Because the involvement of two healthcare personnel did not connect well with the title of the study, the study's results require significant restructure. You may incorporate their feedback into another research project. As a result, all of the themes and subthemes must be readjusted.

Please offer specific demographic information about respondents using a qualitative method. This is necessary to see the variability of the individuals selected for the study.

I will go over the discussion after I have the amended version of the work, especially if the results have been corrected.

REVIEWER 2

This is an important study. The quality of the manuscript can be improved Several grammatical and spelling errors noted. Inconsistencies in the use of DM patients/ diabetes patients and sampling method noted. The recruitment, inclusion criteria for the health care professionals is not included. The findings section needs to be reworked. It is lengthy with repetition and no flow. Reporting the healthcare professionals and the patients' quotes under one theme without a clear description together with lack of introductory sentences before direct quotes distorted the findings section. Please revise. Please consider rewording the conclusion to make the statements shorter, clearer and more impactful to the reader. Kindly see an annotated copy with the comments and suggestions.

This is a qualitative study conducted in a small community. We are very careful of realising the recorded voice online to avoid data breaches of someone recognising the participant's voice. As such, releasing it to a third-party website might leave the participants vulnerable to such. However, if it’s provided upon request, the individual/institution making the request can be requested to sign an undertaking not to release the participant's voice in any repository.

b) If there are no restrictions, please upload the minimal anonymised data set necessary to replicate your study findings as either Supporting Information files or to a stable, public repository and provide us with the relevant URLs, DOIs, or accession numbers.

REVIEWER 1:

I reviewed an article entitled “Perception and coping mechanisms among diabetes mellitus patients at the University College Hospital, Ibadan, Nigeria, during the COVID-19 pandemic”. It was interesting to read. A few changes were required to improve the general structure of the work.

Response: Thank you.

The abstract is relatively long and may exceed the maximum number of words permitted. It might be enhanced by condensing the introductory and conclusion sections. The results should clearly state the themes and subthemes that emerged from the investigation in the first place and please provide a brief explanation for each subtheme.

Overall, you have justified your research nicely in the introduction. However, the method needs to be modified so that it answers the research's objectives and title.

Response: Thank you. We have made few revision to the abstract section. However, the abstract is within the range set by PLoS ONE.

The study's title clearly states that the research mostly featured Dm patients, and you are interested in learning about their perceptions and coping mechanisms while dealing with the management of DM and pandemic covid-19. However, you did include two professional healthcare workers as respondents in your method. Please explain why they were added.

How did you select participants for the qualitative study? Please give a citation for your response.

How did you assure the respondents' diversity?

Response: We have addressed these comments.

Please omit the word “only” in your description of study criteria. Restructure your statement to make the grammar more readable. Restructure your statement to make the grammar more readable.

Response: We have removed “only” from the study area.

Who developed the questions for data collection? How do the questions appear? Please give an example of the questions that were asked. Who verifies each of the questions before they are used? How many times did the verification procedure occur?

Response: The researchers (authors) developed the questionnaires, and the ethnographers assessed its ability to answer the objectives of the study. Pre-testing was done prior to the actual data collection by the researchers in a different facility not used for the data collection.

What if the appointment was cancelled or the participant was unable to keep to the schedule because the interview was held in a hospital setting? How many times did the interview take place in total? How did you conduct the interview? Did you use a local language or English? Please provide specifics.

Response: The interview spanned for at least more than a week, and the participants were informed about this exercise. Hence, the majority of the participants turned up for the interview.

In terms of data analysis, please describe in detail the thematic process that you used in the study. Who checked the interview verbatim and was it shown to the respondents before it was processed further?

Response: We have revised the analysis section.

The four requirements to grow trustworthiness and establish rigors were credibility (internal validity), transferability (external validity/generalizability), dependability (reliability), and confirmability (objectivity), how did you confirm all of these aspects?

Response: We have provided a section under the analysis section describing these four requirements.

Because the involvement of two healthcare personnel did not connect well with the title of the study, the study's results require significant restructure. You may incorporate their feedback into another research project. As a result, all of the themes and subthemes must be readjusted.

Response: The responses have been adjusted to include only in-depth interviews conducted with the DM patients.

Please offer specific demographic information about respondents using a qualitative method. This is necessary to see the variability of the individuals selected for the study.

Response: The authors have addressed this.

I will go over the discussion after I have the amended version of the work, especially if the results have been corrected.

Response: Thank you.

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.
