Reviewer's Responses to Questions

Comments to the Author

1. Does the manuscript provide a valid rationale for the proposed study, with clearly identified and justified research questions?

The research question outlined is expected to address a valid academic problem or topic and contribute to the base of knowledge in the field.

Reviewer #1: Yes

Reviewer #2: Partly

**********

2. Is the protocol technically sound and planned in a manner that will lead to a meaningful outcome and allow testing the stated hypotheses?

The manuscript should describe the methods in sufficient detail to prevent undisclosed flexibility in the experimental procedure or analysis pipeline, including sufficient outcome-neutral conditions (e.g. necessary controls, absence of floor or ceiling effects) to test the proposed hypotheses and a statistical power analysis where applicable. As there may be aspects of the methodology and analysis which can only be refined once the work is undertaken, authors should outline potential assumptions and explicitly describe what aspects of the proposed analyses, if any, are exploratory.

Reviewer #1: Yes

Reviewer #2: No

**********

3. Is the methodology feasible and described in sufficient detail to allow the work to be replicable?

Descriptions of methods and materials in the protocol should be reported in sufficient detail for another researcher to reproduce all experiments and analyses. The protocol should describe the appropriate controls, sample size calculations, and replication needed to ensure that the data are robust and reproducible.

Reviewer #1: Yes

Reviewer #2: Yes

**********

4. Have the authors described where all data underlying the findings will be made available when the study is complete?

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception, at the time of publication. 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

**********

5. Is the manuscript presented in an intelligible fashion and written in standard English?

PLOS ONE does not copyedit accepted manuscripts, so the language in submitted articles must be clear, correct, and unambiguous. Any typographical or grammatical errors should be corrected at revision, so please note any specific errors here.

Reviewer #1: Yes

Reviewer #2: Yes

**********

6. Review Comments to the Author

Please use the space provided to explain your answers to the questions above and, if applicable, provide comments about issues authors must address before this protocol can be accepted for publication. You may also include additional comments for the author, including concerns about research or publication ethics.

You may also provide optional suggestions and comments to authors that they might find helpful in planning their study.

(Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Dear Author, Please consider below suggestions:

1. In the introduction you have given the definition of maternal death. I suggest you give it earlier in the introduction section.

2. In the research question, actually you are searching for the gap of knowledge, and then please mention it properly and mention any potential sub-questions.

3. I do not agree with this type of writing inclusion and exclusion criteria. Actually, it is a kind of repeating the same thing.

4. Please mention the approval of the protocol and funding source.

Reviewer #2: Many thanks for the opportunity to review the manuscript Mapping evidence on factors contributing to maternal and child mortality in sub-Saharan Africa: a scoping review protocol.

I think the authors have develop a protocol which to certain extent meets the requirement for a scoping review protocol.

I am missing the search strategy for all the databases which should be in an appendix. I also think that the suggested PubMed search is not build to capture factors contributing to maternal and child mortality e.g. I don’t see the word cause of death etc.

I don’t understand why you are not including studies published in French as SSA has a huge Francophone population.

For the data extraction – what do the authors mean with “most relevant findings”?

For the reviewer it would be very useful if the manuscript has line numbering.

Why women older than 15 years?

The references used are generally very old e.g. World Health Statistics from 2016. A new report is published very year. The same with reference 9.

I don’t think this review adds much to the literature as we already know why women and children are dying in SSA.

1 It is okay to not include studies published in French, however, you need to justify this. We agree with the reviewer that the justification should have been provided, hence we have now provided it. In short, we will exclude non-English studies as previous studies have shown that it had a minimal effect on the overall conclusions.

REVIEWER ONE COMMENT

1 Reviewer #1: Dear Author, Please consider below suggestions:

In the introduction you have given the definition of maternal death. I suggest you give it earlier in the introduction section. Thank you for this good suggestion, we have now moved the definition of maternal death to the earlier part of the introduction, as suggested. Page 3, Lines 49-52

2 In the research question, actually you are searching for the gap of knowledge, and then please mention it properly and mention any potential sub-questions. Thank you for this suggestion, we have now mentioned the gap of knowledge and potential sub-questions properly. Page 4, Lines 85-86

3 I do not agree with this type of writing inclusion and exclusion criteria. Actually, it is a kind of repeating the same thing. Thanks for the observation. We have re-written our inclusion and exclusion criteria in an unrepetitive manner. Pages 5-6, Lines 107-119

4 Please mention the approval of the protocol and funding source. The requested information has now been incorporated, thanks. Page 11, Line 257

REVIEWER TWO COMMENT

1 Reviewers' comments:

Many thanks for the opportunity to review the manuscript Mapping evidence on factors contributing to maternal and child mortality in sub-Saharan Africa: a scoping review protocol.

I think the authors have develop a protocol which to certain extent meets the requirement for a scoping review protocol.

Thank for your review and comment.

2 I am missing the search strategy for all the databases which should be in an appendix. I also think that the suggested PubMed search is not build to capture factors contributing to maternal and child mortality e.g. I don’t see the word cause of death etc. Thanks for your observation. We have added a pilot search using the PubMed database and also included the word ‘cause of death’ in the search. Page 10-Lines 238-239

3 I don’t understand why you are not including studies published in French as SSA has a huge Francophone population. We have taken an approach by Reviewer One, suggesting that excluding non-English articles is acceptable, provided that proper justification is provided (please see our response to the related query by Reviewer One).

Page 6, Lines 114-115

4 For the data extraction – what do the authors mean with “most relevant findings”? Upon reflection, we have released that this phrase ‘most relevant findings’ may be confusing, hence we have removed it from our data extraction form and replaced it with ‘key findings’. During the data extraction process we will include the key outcomes from each article included in the study. Page 10, Line 240

5 For the reviewer it would be very useful if the manuscript has line numbering We have inserted line numbering. Whole Manuscript

6 Why women older than 15 years? We chose this age due to the high prevalence of teenage pregnancy in SSA in this age group. The categorisation of 15-24 years or 15-19 years (in the case of studies on teenage issues) is common in scientific papers. So, we expect that most studies reporting on maternal and child health issues may rarely capture ages below 15 years.

7 The references used are generally very old e.g. World Health Statistics from 2016. A new report is published very year. The same with reference 9. Thanks, we have updated the references. Whole Manuscript

8 I don’t think this review adds much to the literature as we already know why women and children are dying in SSA.

This study is trying to challenge the very dismissive perception that we know the problems in SSA and not be opened to observing the emerging trends. Greater emphasis still needs to be paid to maternal and child health issues, as these remain serious public health problems. Unless, this maternal and child health issues remain in the agenda of scientists, policy makers, advocacy groups and interventionists may easily lose sight to these important issues. .
