Title: Association between plant-based dietary index and disease severity in patients with
ulcerative colitis: A cross-sectional study
Version: 1 Date: 02 Jul 2024
Reviewer's report:
1 The number of included cases is too small, which affects the analysis results
2 Most studies classify  individual plant-based dietary index (PDI)  into four categories (in
quintiles), why did you use three categories (in tertiles)?
3 The extent of disease in UC was defined according to the Montreal classification as E1:
proctitis (proximal extent to the sigmoid colon), E2: left-sided (to the splenic flexure) or E3:
extensive disease (beyond the splenic flexure). You were still using the old classification
standards. Furthermore,UC patients treated with biological agents were excluded?
4 Result is too simple,subgroup analysis is required.
