Additional Editor Comments:

The manuscript titled "The Relationship Between Maternal Uterine Artery Doppler Ultrasound During the Second and Third Trimesters and Infant Cognitive Development at One Year of Age: Findings from a South African Prospective Cohort Study" is well-written and clear. The study’s aim is compelling, and the methodology is appropriate. I enjoyed reading it.

To enhance the manuscript, I suggest the following revisions:

Please avoid using abbreviations in the abstract.

We have revised the abstract to remove all abbreviations, ensuring clarity and alignment with journal guidelines.

In the Ethics section, specify whether consent for participation and publication was obtained, given the prospective nature of the study.

We have added the following statement to the Ethics section (lines 220-222):

“Participants provided written informed consent, including approval for the use of their data in future studies. Data from those who did not provide consent were not used”.

Expanding on the clinical and research implications in the Discussion section would be beneficial.

We appreciate this valuable suggestion and have expanded on the clinical implications in the Discussion section. Specifically, we have emphasized the importance of obstetricians and maternal-fetal specialists being aware of the potential for developmental delay in children with abnormal uterine Doppler findings during pregnancy. This awareness can help ensure timely assessments and early intervention where needed (Discussion, lines 390-93).

We also sincerely thank the editor for their time and consideration in reviewing our manuscript.

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: the manuscript is interesting despite not only UtA are correlated with neurodevelopmentall delay but also birth whicht, inasnuch the null hypothesis of the study has to be changed and highlight the outcomes better for reders

We sincerely appreciate your thoughtful feedback and for recognizing the value of our manuscript. Regarding your comment on the null hypothesis, we would like to clarify that our study hypothesis is explicitly stated in the final paragraph of the introduction.

Reviewer #2: The authors have done an excellent job in writing this article. It is well-written, and the subject matter is highly relevant. However, two revisions are recommended. First, a paragraph discussing the clinical implications of the findings should be included. Second, further elaboration on suggestions for future research would strengthen the manuscript, particularly expanding on the potential for studies with larger sample sizes, which is briefly mentioned.

We thank Reviewer #2 for their helpful revisions, which we agree will improve the quality of our manuscript. We have added a comment on the clinical implications of the findings: “Obstetricians and Maternal-Fetal specialists should be informed of the possibility of developmental delay in children when abnormal uterine Doppler assessments had been recorded in the mother during the pregnancy, to ensure that these children are carefully assessed at appropriate times and remedial treatment instituted when necessary.” (line 378-81)

We have further amended the title of the ‘Strengths and Limitations’ section within the Discussion to be ‘Strengths, Limitations and Future Directions’ to accurately reflect the content of this sub-section. The following points have been added to this section to reflect on future directions for research, with a focus on sample size of future studies:

- “It would be interesting to conduct a study of similar design which stratifies participants by term delivery to examine how much of the effect observed is due to preterm birth.” (line 305-6)

- “Future research with larger sample sizes is required to elucidate the associations between placental function and offspring cognitive development. Larger sample sizes will afford the findings with increased statistical power and provide the opportunity to include a truly generalisable sample.” (line 308-11)
