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: Dear authors thanks for this interesting review. In general, this review is well written. However, I have some comments and questions

1.Your review needs major language edition

2.Please incorporate your review Prospero registration number in abstract section

3.Please put the citation for the PRISMA guideline you used under method section. Is that PRISMA guideline 2020 or not?

4.If you used the PRSMA guideline 2020, some components were missed for example Certainty assessment

5.Please avoid the term data analysis and process in method section rather use Synthesis methods and Reporting bias assessment

6.Avoid a paragraph ‘’Fixed effect model would have been used 187 if studies were homogeneous’’

7.What were the limitations of your review?

8.Lastly, please use PRISMA 2020 https://pubmed.ncbi.nlm.nih.gov/33782057/ guideline and rewrite your review and meta-analysis

Thank you

Reviewer #2: Your manuscript is full of self-plagiarism from your previous published work (Kasahun AW, Zewdie A, Shitu S, Alemayehu G. Vaccine cold chain management practice and associated factors among health professionals in Ethiopia: systematic review and meta-analysis. Journal of Pharmaceutical Policy and Practice. 2023 Dec;16(1):1-0.).

You used a mnemonic PICO (population, intervention, control, outcome), wrongly. Since your review is on prevalence studies, you need to use CoCoPop (condition, context, population). I have doubt on your inclusion criteria since you use PICO. I need to see your search strategies and search terms that you use for each database.

On methods part line 118 needs citation.

You use Joanna Briggs Institute for data extraction, why not for quality assessment and analysis too?

Dear Academic editor of PLOS ONE and the reviewers, we are highly indebted to your important comments and queries of clarifications for enriching our manuscript. The following statements are tailored to address all of your reflections point by point in their order of appearance from the forwarded comments.

1. Please ensure that your manuscript meets PLOS ONE's style requirements

A: we revised the manuscript in accordance with PLOS ONE style requirements

2. In your Data Availability statement, you have not specified where the minimal data set underlying the results described in your manuscript can be found. PLOS defines a study's minimal data set as the underlying data used to reach the conclusions drawn in the manuscript and any additional data required to replicate the reported study findings in their entirety. All PLOS journals require that the minimal data set be made fully available. For more information about our data policy,

A: Our manuscript solely depends on the previous research works; as a result, we have not primary data set for it. But as additional information file, we will upload the extracted data set that we used for estimating the pooled prevalence of the outcome variable.

3. Please upload a new copy of Figure 2 and 4 as the detail is not clear.

A: we have uploaded clearer version of fig.2 and fig.4

4. PLOS requires an ORCID iD for the corresponding author in Editorial Manager on papers submitted after December 6th, 2016. Please ensure that you have an ORCID iD and that it is validated in Editorial Manager. To do this, go to ‘Update my Information’ (in the upper left-hand corner of the main menu), and click on the Fetch/Validate link next to the ORCID field. This will take you to the ORCID site and allow you to create a new iD or authenticate a pre-existing iD in Editorial Manager. Please see the following video for instructions on linking an ORCID iD to your Editorial Manager account:

A: ORCID iD of the corresponding author is updated and linked to to the Editorial Manager.

R1: Please incorporate your review Prospero registration number in abstract section

A; Thanks, we incorporated the PROSPERO registration number on the abstract section of the revised manuscript

R1: Please put the citation for the PRISMA guideline you used under method section. Is that PRISMA guideline 2020 or not?

A: Yes, we have used PRISMA 2020 guideline, and appropriate reference is cited on the revised version.

R1: If you used the PRSMA guideline 2020, some components were missed for example Certainty assessment

A: Thank you; we have included certainty assessment methods and its findings on the method and result section of the manuscript respectively.

R1: Please avoid the term data analysis and process in method section rather use Synthesis methods and Reporting bias assessment

A: thanks, Corrected accordingly

R1: Avoid a paragraph ‘’Fixed effect model would have been used 187 if studies were homogeneous’’

A: Thanks, removed on the revised version

R1: What were the limitations of your review?

A: We included the limitations of our review at the end of the discussion on the revised version of the manuscript. The result of this systematic review and meta-analysis is based on few studies; as a result it may not show the true magnitude of the outcome variable. It may possibly different if many more studies were done and included in this meta-analysis and review. Above all, this result is solely depends on the already available data from previous studies, as a result the limitation and quality of the previous researches have an impact on our findings.

R1: Lastly, please use PRISMA 2020 https://pubmed.ncbi.nlm.nih.gov/33782057/ guideline and rewrite your review and meta-analysis

A: thank you, we have revised in accordance with the referred guideline (PRISMA2020)

R2: I have seen self-plagiarism from your previous published work (Kasahun AW, Zewdie A, Shitu S, Alemayehu G. Vaccine cold chain management practice and associated factors among health professionals in Ethiopia: systematic review and meta-analysis. Journal of Pharmaceutical Policy and Practice. 2023 Dec;16(1):1-0.).

A: Thanks, There was some text overlap from the previously published article on vaccine cold chain management practices as the condition understudy is closely related. We have made a meticulous revision on those issues on the revised version.

R2: You used a mnemonic PICO (population, intervention, control, outcome), we use it for effectiveness studies to develop question, instead of using CoCoPop (condition, context, population) for prevalence studies. I have doubt on your inclusion criteria since you use PICO. I need to see your search strategies and search terms that you use for each database.

A: Thank you, we actually used CoCoPop/PEO, though it is wrongly mentioned as PICO in the submitted manuscript, unfortunately we retained the template that we have used for the other review. We have corrected it on the revised version of the manuscript. The objectives of our review are: to determine the pooled magnitude of health professionals’ knowledge on vaccine cold chain management and to identify its associated factors. As the review has prevalence and risk assessment objectives we have used CoCoPop/PEO guide.

Condition: Knowledge on vaccine cold chain management

Population: Health professionals

Context: Ethiopia

Exposure: Are socio-demographic, health facility and other factors that negatively or positively affect health professionals’ knowledge on vaccine cold chain management; it includes level of training, professional category, on job training, supervision and others.

Outcome: Health professionals’ knowledge on vaccine cold chain management which is determined using a composite of items

R2:. I need to see your search strategies and search terms that you use for each database.

A: Kindly find some of the search terms that we used in each data base. Furthermore, a hand search was made on references of retrieved studies using the mentioned search terms.
