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 paper represents a major effort to establish the cutoff score for the Hong Kong Version of the Montreal Cognitive Assessment for the visually impaired and to assess the cognitive performance of nursing home elderly residents with visual impairment in Hong Kong. I believe that the goal of the study is worthwhile and appropriate for the readership of the PLOS ONE. The study is providing important data that can be applied in clinical practice. However, major concerns should be addressed before resubmission.

1. The manuscript should be checked by professional editing service before resubmission.

2. The introduction section is long. While comprehensive, the introduction could be more impactful by focusing on the most essential background information.

3. The quality of the image in figure 1 is poor and should be improved.

4. The Cantonese version of the Mini Mental State Examination was described in the manuscript in different ways as CMMSE-VI, CMMSE, The modified CMMSE. The authors need to unify the term used to describe the tool throughout the manuscript.

5. Regarding the methodology section: there are many major concerns as

o While restricting the study to individuals with severe visual impairment simplifies the analysis by minimizing confounding factors, it also limits the generalizability of the findings. This point should be acknowledged in the limitations section.

o Another limitation of the study was including those with no information regarding their education level. 31 cases that comprises 25.2% of the sample recruited.

o Restricting the study to cases in nursing homes will prevent results generalizability to elderly within community, however; this limitation was highlighted in the limitations.

o The absence of data on depression and delirium, known to affect memory and attention, makes it difficult to draw definitive conclusions about the cognitive abilities of the cases. Were the cases with depression and /or delirium excluded from the study?

o The Cantonese version of the Mini Mental State Examination (as cited in reference 27) recommended a cut-off score of 19/20 that yielded a high sensitivity rate of 97.5 and an equally good specificity of 97.3. This appeared to be the best cut-off score for their sample of subjects. Moreover, those cut off scores were obtained without adjusting for visual impairment thus can’t be applied to your sample.

o Linear regression would adjust better for age and educations than using the percentiles, then it would be better to add tables 2,3,4 as supplementary data.

Reviewer #2: Dear Authors

I read your work entitled “The Hong Kong version of Montreal Cognitive Assessment for the visually impaired (HKMoCA-VI): Its cutoff and a survey on the cognitive functioning of visually impaired elderly in residential homes” and here I enclose my recommendations to you:

1. Please have the text checked for language issues, since several mistakes have been tracked. A native speaker of English or a professional Editing company would help towards this.

2. Abstract General comments: The Abstract need a reconstruction and Methods section and the results section.

3. The “Introduction” section: It would be beneficial for the authors to include more precise information in the introduction about the gaps of the existing knowledge and how this study attempts to fill them. An augmentation of the existing literature in the text would benefit more for the Introduction and it will strengthen the rational of this study. Additionally, I suggest the Authors to focus more on the HKMoCA-VI and why it is so important.

4. The “Methods” section: The Authors report criteria that are not based on the existing literature. I suggest them to elaborate this.

5. The “Methods” section: It is strange that the Author do not report which groups severed as clinical and the controls in this study.

6. The “Discussion” section: The Authors are developing this section according to their results and connect them in an adequate manner to the existing knowledge but as we can see most of the studies used a control group that in this study is not clearly reported. I suggest the Authors to address that as well. This will help the Authors to strengthen more their work.

Thank you.

I believe that the goal of the study is worthwhile and appropriate for the readership of the PLOS ONE. The study is providing important data that can be applied in clinical practice. However, major concerns should be addressed before resubmission.

1. The manuscript should be checked by professional editing service before resubmission.

Response: The manuscript has been checked by professional editing service before resubmission.

2. The introduction section is long. While comprehensive, the introduction could be more impactful by focusing on the most essential background information.

Response: The introduction section has been revised to focus on the development of HKMoCA-VI and the rationales (p. 5, lines 79-93), with the implications of findings stressed in Discussion (p. 15, lines 225-226, 231-234).

3. The quality of the image in figure 1 is poor and should be improved.

Response: The quality of the image of Figure 1 has been improved and re-submitted.

4. The Cantonese version of the Mini Mental State Examination was described in the manuscript in different ways as CMMSE-VI, CMMSE, The modified CMMSE. The authors need to unify the term used to describe the tool throughout the manuscript.

Response: The term ‘CMMSE’ has been used consistently throughout the manuscript.

5. Regarding the methodology section: there are many major concerns as

o While restricting the study to individuals with severe visual impairment simplifies the analysis by minimizing confounding factors, it also limits the generalizability of the findings. This point should be acknowledged in the limitations section.

Response: This point has been acknowledged in the limitations section (p. 19, lines 304-306).

o Another limitation of the study was including those with no information regarding their education level. 31 cases that comprises 25.2% of the sample recruited.

Response: This point has been addressed in the limitation (p. 18, lines 293-295).

o Restricting the study to cases in nursing homes will prevent results generalizability to elderly within community, however; this limitation was highlighted in the limitations.

Response: Thanks for raising this point out, which has been included as one of the limitations.

o The absence of data on depression and delirium, known to affect memory and attention, makes it difficult to draw definitive conclusions about the cognitive abilities of the cases. Were the cases with depression and /or delirium excluded from the study?

Response: We excluded elderly with a diagnosis of depression, delirium or other mental illness (p. 9, lines 141-142).

o The Cantonese version of the Mini Mental State Examination (as cited in reference 27) recommended a cut-off score of 19/20 that yielded a high sensitivity rate of 97.5 and an equally good specificity of 97.3. This appeared to be the best cut-off score for their sample of subjects. Moreover, those cut off scores were obtained without adjusting for visual impairment thus can’t be applied to your sample.

Response: The method for determining the HKMoCA-VI has been explained (p. 10, lines 157-165, p. 11, lines 182-190, 196-213).

o Linear regression would adjust better for age and educations than using the percentiles, then it would be better to add tables 2,3,4 as supplementary data.

Response: Linear regression has been conducted to account for the effects of age and education on the scores (p. 11, lines 182-190). We would still keep tables 2-4 in the main text for the clinicians’ easier reference.

Reviewer #2: Dear Authors

I read your work entitled “The Hong Kong version of Montreal Cognitive Assessment for the visually impaired (HKMoCA-VI): Its cutoff and a survey on the cognitive functioning of visually impaired elderly in residential homes” and here I enclose my recommendations to you:

Response: The manuscript has been checked for language accuracy.

2. Abstract General comments: The Abstract need a reconstruction and Methods section and the results section.

Response: The abstract has been reconstructed (p. 2, lines 25-31, 37-39).

3. The “Introduction” section: It would be beneficial for the authors to include more precise information in the introduction about the gaps of the existing knowledge and how this study attempts to fill them. An augmentation of the existing literature in the text would benefit more for the Introduction and it will strengthen the rational of this study. Additionally, I suggest the Authors to focus more on the HKMoCA-VI and why it is so important.

Response: The Introduction section has been revised to focus on HKMoCA-VI (p. 5, lines 79-93; p. 7, lines 115-118).

4. The “Methods” section: The Authors report criteria that are not based on the existing literature. I suggest them to elaborate this.

Response: Inclusion and exclusion criteria have been elaborated (p. 8, lines 127-144).

5. The “Methods” section: It is strange that the Author do not report which groups severed as clinical and the controls in this study.

Response: We attempted to classify the participants into dementia group and non-dementia group according to their medical diagnosis (p. 8, lines120-125). Nevertheless, due to the under-recognition of dementia in Hong Kong while CMMSE has been used to determine cut-off of HKMoCA-VI. This point has been discussed in the Discussion section (p. 17-18, lines 278-285).

6. The “Discussion” section: The Authors are developing this section according to their results and connect them in an adequate manner to the existing knowledge but as we can see most of the studies used a control group that in this study is not clearly reported. I suggest the Authors to address that as well. This will help the Authors to strengthen more their work.

Response: This point has been addressed in the Discussion section (p. 17-18, lines 278-285).

Reviewer #1: This paper represents a major effort to establish the cutoff score for the Hong Kong Version of the Montreal Cognitive Assessment for the visually impaired and to assess the cognitive performance of nursing home elderly residents with visual impairment in Hong Kong. I believe that the goal of the study is worthwhile and appropriate for the readership of the PLOS ONE. However, minor changes are required.

• The introduction includes some redundant information. Consider streamlining it to focus on the core research question and the rationale for the study.

• The manuscript would benefit from some English editing to ensure clarity and flow. Consider using a professional editing service or collaborating with a colleague with strong English language skills.

• Currently, the inclusion and exclusion criteria are presented in separate bullet points. For improved readability, consider combining them into a single, well-structured paragraph. This will allow you to explain the rationale behind each criterion more effectively.

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.
