3. Point-by-point response to Comments and Suggestions for Authors

Comments 1: This is a retrospective analysis of a prospective study. The AA must give the reference of the previous published papers related to the original study. The design prevents from drawing solid conclusions, so the consistency of the results are questionable and the priority for publication is quite low. Nevertheless, additional information about potassium intake in peritoneal patients are given.

Response 1: Thank you for pointing this out. We have cited previously published articles in the discussion, with reference numbers 22 and 23, respectively. However, the study design has been fixed at the beginning of the study, and we described the study details in the methods part as much as possible. We will learn from the experience and make it as well as possible in the future study design.

Response 1: Thank you for your comments.
