Title: Effectiveness of switching endoscopists for repeat surveillance colonoscopy: a
retrospective study
Version: 1 Date: 05 Sep 2023
Reviewer's report:
In this version of manuscript, the authors have made some revision from previous comments.
However, I still strongly recommend the authors should provide baseline (index) colonoscopy
data from D- and S- group rather than the polyp per colonoscopy only.  The comparison of
two groups of follow-up colonoscopy is only meaningful with adequate information of index
colonoscopy to exclude obvious biases.
