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: I thank the authors for their challenging work. However, the paper needs lexical review, for example the choice of the words “ cardiopathic “ in page 5, “ always “ in page 6 and “ typology “ in page 8 is less familiar as the usual scientific lexicon.

Reviewer #2: - Overall, the research question is interesting however, major comments should be addressed and clarified.

- The readability and syntax of the manuscript will be substantially improved if it is reviewed by a formal translation agency or by a colleague whose first language is English.

Abstract:

- Short background on the DOC.

- Define VS and MCS.

- The design of the study should be described in the methods.

- The criteria of the subjects should be demonstrated e.g. age, genders.

- Did the author make two classifications in this study? VS and MCS, then severe and non-severe. Please, clarify

- Methods need more information.

- The size is very small to provide a conclusion.

- Change 16/18 to 16 and 2/18 to 2.

- Important differential results with p-values should be demonstrated.

- The conclusion should more concise to be related to the objective of the study.

Introduction:

- The introduction needs to be analyzed and rewritten.

- More information should be clarified about the DOC and its relation to SARS-CoV-2.

- The objective of the study is very important however the importance of the study still need more clarification in the introduction section.

- What was the hypothesis of the study.

Methods:

- What is the design of the study?

- What were the inclusion and exclusion of the study to select the participants?

- Did the author calculate the sample size and power of the study?

- Methods section is very poor and needs more information and description.

- Statistical analysis: What is the statistical method used to assess the normal distribution of the collected data. "The significance threshold" is inadequate expression. Please, change it to "the level of significance".

Results:

- Results need to provide answers to the questions raised/researchable problem.

- Results need to follow accuracy, brevity, and clarity.

- Kindly frame it along the following elements of results.

Discussions:

- The introductory paragraph should demonstrate the main findings of the study.

- The findings should be compared with previous or related studies.

- Implications of the study should be explained.

- The main limitation of the study design was not demonstrated.

- Briefly, the discussion section need major revisions.

- We reported the most important differential results with p-values.

- We revised the conclusion, as suggested.

3) Introduction:

- We revised the introduction, as suggested.

- No data, to date, were reported about DOC and relation to SARS-CoV-2: this is the first study. In addition this is a retrospective, longitudinal, observational study, that showed the impact, in a descriptive way, of a sudden SARS-COV2 infection. No power analysis was performed, because all patients of DOC Unit, were consecutively enrolled.

- We revised the report of objective of the in the introduction section.

- We better explained the hypothesis of the study.

4) Methods:

- Design of the study: this is a retrospective, longitudinal, descriptive, observational study. It was reported.

- We included in the study all patients admitted to our DOC rehabilitative unit, at the time the SARS-COV2 outbreak broke out. For this reason, no particular inclusion and/or exclusion were applied.

- The response is very similar to the previous point: we included in the study all patients admitted to our DOC rehabilitative unit, at the time the SARS-COV2 outbreak broke out. For this reason, no sample size and power of the study were calculated.

Reviewer #1: Thank you for this longitudinal small-scale study. I would like the inclusion of the following in the retrospective paper: the steroid regimen use and dose regimen in the 18 patients, the body mass index for the 18 patient as it has been proven that an increased BMI contributes to increased mortality related to COVI-19 chest infection, and finally the inclusion of the metabolic profile including glycemic state control, electrolytes and BP control as all these could contribute to the encephalopathy cycle state of the patients.

Reviewer #2: Appreciating the authors for address the required corrections. However, some minor corrections should be addressed:

- I suggest authors add "pilot" to the design of the study in accordance with the small sample size.

- The methods section should be re-framed and re-arranged as the following:

a. Study design, setting

b. Participants

c. Intervention/issue of interest (exposure)

d. Comparison

e. Ethics and endpoint

f. Statistical analysis

- Clarify what the statistical method used to assess the data normality.

- Cite the Statistical Software used in data analysis.

Reviewer #2:

We thank the reviewer for the time spent to revise the manuscript. We revised the paper, as suggested.

Statistical section, already reports what was requested by the reviewer:

- statistical method used: "Mean and standard deviations (SD) were used for normally distributed data and median and range for data that were not normally distributed. Continuous variables were compared by using Wilcoxon rank sum test. Proportions for categorical variables were compared using χ2 test. Because of the small sample size, ordinal, interval and ratio measures are presented as median and range";

- statistical software used: "All statistical analyses were performed using R (version 3.3)".

We thank you again for your consideration of our work and look forward to hearing from you in due course.

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.
