5. Review Comments to the Author

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: This work aims to establish deep learning models for classifying the presence of endometrial tumors in hysteroscopic images. And an average diagnostic accuracy exceeding 90% was realized when using the combination of 72 trained DNN models. However, I have the following concerns:

1)I am a bit curious why they use this deep learning architecture for endometrial tumors detection, rather than shallow machine learning models.

2)There are several errors in this manuscript, such as “The corresponding sensitivity and specificity equaled 91.66% and 89.36, respectively”. Is it 89.36%? The authors should double check the manuscript.

3)The manuscript should give the overall model architecture.

4)The metric method for the model is too simple, the author should add more metric method. Please refer to several literatures, such as:

Pang Shanchen, Ding Tong, Qiao Sibo, Meng Fan, Wang Shuo, Li pibao, WangXun . A novel YOLOv3-arch model for identifying cholelithiasis and classifying gallstones on CT images,2019, Plos one, 6(14):e0217647.DOI: 10.1371

Reviewer #2: In the paper, authors present an artificial-intelligence-based system to detect the regions affected by endometrial cancer automatically from hysteroscopic images. The diagnosis accuracy is increased. However, there are some details that can be improved.

The models used in the paper are not presented well.

The set of threshold value is 50, maybe you can explain some details about that.

The writing of the paper should be taken care. For example, the text size on the tables, the text-transform on subtitle of page 7.

Revision 1

Reviewer #1:

This work aims to establish deep learning models for classifying the presence of endometrial tumors in hysteroscopic images. And an average diagnostic accuracy exceeding 90% was realized when using the combination of 72 trained DNN models. However, I have the following concerns:

Comment1

I am a bit curious why they use this deep learning architecture for endometrial tumors detection, rather than shallow machine learning models.

Response 1

We appreciate your critical comments and useful suggestions. Deep learning is highly anticipated in the medical field because deep learning techniques are particularly suitable for image analysis. They can be used for classification, image quality improvement, and segmentation of medical images. In contrast, shallow machine learning is not suitable for image recognition. We have added this information to the revised manuscript considering your comment (Lines 66-69).

Comment2

There are several errors in this manuscript, such as “The corresponding sensitivity and specificity equaled 91.66% and 89.36, respectively”. Is it 89.36%? The authors should double check the manuscript.

Response 2

We appreciate your critical comments and useful suggestions. It is 89.36%(Lines36). We have corrected the oversight.

Comment3

The manuscript should give the overall model architecture.

Response 3

We appreciate your critical comments and useful suggestions. We have added the overall architecture of the model (Figure2) in accordance with your suggestion.

Comment4

The metric method for the model is too simple, the author should add more metric method. Please refer to several literatures, such as:

Pang Shanchen, Ding Tong, Qiao Sibo, Meng Fan, Wang Shuo, Li pibao, WangXun . A novel YOLOv3-arch model for identifying cholelithiasis and classifying gallstones on CT images,2019, Plos one, 6(14):e0217647.DOI: 10.1371

Response 4

We appreciate your critical comments and useful suggestions. We have added the metric methods in accordance with your comments. F-score and Precision have been added to Table 2. In addition, the description and structure of each network are also given (Tables S4, S5, S6, S7, Lines 164-179).

Reviewer #2:

In the paper, authors present an artificial-intelligence-based system to detect the regions affected by endometrial cancer automatically from hysteroscopic images. The diagnosis accuracy is increased. However, there are some details that can be improved.

Comment1

The models used in the paper are not presented well.

Response 1

We appreciate your critical comments and useful suggestions. We have added the overall architecture of the model (Fgure2) to provide further details of the model used. In addition, the description and structure of each network are also given (Tables S4, S5, S6, S7, Lines 164-179).

Comment2

The set of threshold value is 50, maybe you can explain some details about that.

Response 2

We appreciate your critical comments and useful suggestions. The threshold was taken from the points where the malignant score intersects with the other scores rather than the point where the average of two scores was the best, because the threshold should be set lower to reduce oversight cases in the actual clinical devices. We have added this information to the revised manuscript considering your comment (Lines 152-154).

Comment3

The writing of the paper should be taken care. For example, the text size on the tables, the text-transform on subtitle of page 7.

Response 3

We appreciate your critical comments and useful suggestions. We have revised the manuscript in accordance with your suggestion and PLOS ONE's style requirements.

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.
