Title: Association Between Dietary Phosphorus Intake and Chronic Constipation in Adults:
Evidence from the National Health and Nutrition Examination Survey
Version: 4 Date: 26 Aug 2022
Reviewer's report:
I think this is an interesting topic. However, the biologic plausibility is very weak. No possible
mechanism was discussed. The language is below the level for publication, for example “use
was defined as frequent”, “We set the continuous variables as categorical variables…”,
Specific comments:
1. The sentence is not clear for me, “Dummy variables were used to indicate missing covariate
values”
2. The sensitivity analysis was inconsistent with the main results, “Dietary phosphorus intake
was not associated with these three conditions.”
3. Discussion: More elaboration on the possible mechanisms are expected.
