Title: The Association between Non- and Pro-Healthy Diet Indices and the Risk of Colorectal
Cancer: A Case-Control Study
Version: 1 Date: 17 Oct 2024
Reviewer's report:
Overall, I think this paper has the quality necessary to be published, and the topic is relevant.
Nonetheless, I have several mostly small recommendations, and a few more critical ones.
- Methods section: Please clarify how the scores are assigned to the PHDI-10 and NHDI-14
indices. Could you explain the scoring system in more detail? Specifically, how are the scores
for the food groups calculated for each index, and how is the final score determined? The article
mentions that "the PHDI-10  ....is linked to the frequency of consuming 10 food groups", but it
is unclear how the frequency of consumption is converted into points. Could you provide more
information on how the frequency is scored for each food group in both indices?
- The term "matched-controls" could be used for "controls."
- It is unclear how the "vegetable and meat cooking methods" is a confounding factor. Can you
please clarify?
- A strength to be presented is the matched-control group, where variables such as age and sex
were matched with the cases.
