Reviewer #1: 1. Sample size calculated by WHO calculator is 380 assuming a response rate of 50%, confidence interval (CI) 95%, Z as 1.96, and margin of error d as 5% by assuming 5000 deliveries occurred per annum in obstetrics and gynecology unit as per unit annual statistics – VERIFY AND INCLUDE THE CALCULATION IN THE TEXT

2. Explain the sampling method

3. Individual scoring of 10 and above were categorized as excellent whereas score below 10 were considered as poor knowledge – HOW WAS THE CUT OFF DETERMINED

4. QUESTIONNAIRE – 21 ITEM QUESTIONNAIRE – Explain the validation process

5. The attitude section consisted of three questions, and the response of each item collected on a 3 point Likert scale as follows 0 (“Disagree”), 1 (“Undecided”), and 2 (“Agree”) – UNDECIDED CATEROGRY IN LIKERT SCALE IS NOT UNIVERSALLY FOLLOWED, BETTER TO BE CONVERTED AS NEAUTRAL

6. The total score ranged from 0 to 6 with an overall greater score indicates more positive attitudes towards the COVID-19. A cut off level of ≥ 5 was set for more positive attitudes towards the prevention of COVID infection – HOW WAS CUT OFF ARRIVED?

7. The reliability of the questionnaire checked by conducting a pretest among pregnant women by taking 5% of the sample size.

8. STUDY TOOL – The 21 item questionnaire – Validation process is not explained in the article.

9. Data was entered and analyzed using SPSS version 21. Data was analyzed by using SPSS 19. – DESCRIBE THE VERSION CLEARLY AND MENTION THE LICENSE AGREEMENT

10. Calculated sample size is 380, but the results were given only for 377 due to 3 missing data which is less than optimum sample size – Author has to view this seriously as sampling and sample size determines the internal and external validity of any quantitative study.

Reviewer #2: Summary:

The study is a well-grounded scientific research to assess the Knowledge, attitude and practice regarding COVID 19 among pregnant mothers. The findings of the study will be useful in identifying and filling the gaps in knowledge regarding COVID 19 among pregnant mothers.

Background:

1. WHO, ARDS and KAP has to be expanded for the first time in the manuscript before using them as abbreviations thereafter.

2. Since study has been completed the phrase “study has been planned” can be avoided. Instead “Study was done” can be used.

3. Grammatical errors are present throughout the background section which needs to be addressed.

4. COVID – 19 has to be represented uniformly in capital letters throughout the manuscript.

5. The Justification for the study could be explained in more detail with detailed statistics regarding COVID 19 related deaths among preganant mothers - Globally, Nationally and in the area of study.

Methods:

1. More explanation is required regarding the sample size calculation. (Eg: Reference for WHO sample size calculator)

2. Since the questionnaire is self-made and not standardised, Cronbach alpha and rationale behind choosing the cut-off has to be mentioned in the manuscript. The author could explain whether they used median/mean or interquartile range of the scores to choose the cut-offs.

3. In page 5, line 115, terms like “will be checked and reviewed” has to be avoided as the study is completed.

4. Sampling method and study duration are not mentioned in the methods section.

5. The author could provide details regarding the language in which questionnaire was used.

6. Details regarding the mode of interview could be provided by the author. They could mention whether the participants filled on their own or an investigator asked questions and filled the form.

Results:

1. In the results section, Table 1 could to be cited in Page 6, Line no:115 to give readers that the details are present in frequency table.

2. In figure 1, the numbers looks pixelated and not visible. The authors could provide an image with good clarity so that, the numbers looks readable.

3. The authors could give details regarding the participants who gave no answer in attitude and practice section and how those responses were used in analysis.

4. The authors could interpret the beta coefficients in details to add value to the interpretation of the findings.

5. In table 5, since 0 is present in many of the cells, the authors could give details on the statistical test in the univariate analysis used to establish association between variables.

Discussion:

1. Repetition of findings mentioned in the results could be avoided in the discussion. Instead a gist can be given and discussed in detail with relevant study comparisons.

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.
