Reviewer #1: Report of the article " YouTube as a source of information on ectopic pregnancy : a qualitative and quantitative analysis".

The article "YouTube as a source of information on ectopic pregnancy : a qualitative and quantitative analysis" deals with a contemporary topic of great interest, especially for those who work with non-formal health education.

Recommendation to authors:

[1. Introduction

The authors need to improve the introduction of the article a lot.

It is necessary to better contextualize the problem and present epidemiological data on ectopic pregnancy. It is not enough simply to state that this can be a fatal pregnancy if left undetected, and that this is mainly a problem in developing countries. I consider it fundamental that the authors present data on ectopic pregnancy in some countries, this will qualify the statements made. For example, show data on deaths and ectopic pregnancies in developed and developing countries.

In the introduction, the authors should make clear the objective of the article and present the research questions.

[2] Methodology

The methodology is well described, however, I recommend that the authors place in a supplementary file a list of all the videos that were selected for the study. This is important to ensure method replication as well as research transparency.

Authors should create a subsection to better explain the DISCERN tool.

[3] Related works

Authors must include a related work section. It is important to know if there are other works and what these works are doing different from the one presented by the authors.

The related work section should be a section where the authors will deepen the discussion on topics based on the works found.

Authors can use more recent works, between 2019 to 2023 and make a critical analysis of the works. The authors state in the discussion that this article was the first to evaluate data from YouTube videos on ectopic pregnancy. However, to better qualify this statement, the authors must present it in this section of related works.

[4] Discussions

The authors make the following statement in the discussion: "YouTube’s algorithm might skew the order of the top 30 videos, as the videos order changes following the viewing of previous videos. This constitutes a selection bias."

I agree that the display of videos changes depending on the YouTube algorithm. However, why would that be a problem? The authors should explain this part better - only the issue of bias in the selection of videos is not enough.

Finally, the authors must include in the discussion a list of recommendations so that a video has quality and at the same time can dialogue (be understandable) with the population (accessible content). It is necessary to deepen this point a little in the discussion and talk about non-formal education in health. The authors talk about this in the conclusions, but in a very superficial way.

Reviewer #2: 

Dear Authors

I begin by congratulating the authors for the work presented.

Great impact on women's health, mental health and public health in general.

Some questions:

- in table 2 the number of likes is one of the most complex variables. Very asymmetrical;

- in table 3, I suggest you include the year of production of the video (the content may be less or more updated);

Conclusions can be improved. as a suggestion the involvement of the university and health professionals in the execution of these videos.

They must include the sustainable development goals (Agenda 2023) to reinforce the pertinence of the theme and the objectives of this article.

Reviewer #1: The authors endeavored to meet the recommendations. Therefore, I am in favor of accepting the article for publication in this journal.

[Only as a suggestion] I believe that the authors could still improve the conclusions for the last version of the article, before publication. For example, talking about future work on this topic, what would be the new paths for research in this area and what is the importance of this model of non-formal education.

Reviewer #2: Congratulations to the authors.

They effectively answered the questions asked. Making it a complete article.

Article relevant to science.
