Title: Impact of obesity in colorectal endoscopic submucosal dissection: single-center
retrospective cohort study
Version: 3 Date: 20 Jan 2021
Reviewer's report:
Thank you the authors for consideration of reviewing according to my comments. There are
some minor suggestions that I hope to improve this revised version, as follows.
1. Please rigorously check the typo; ie. in the Abstract, Method section (BMI < 25 kg/m2), in
the Result line 7 (BMI of 30 kg/m2 or more),  the number of cases and lesions in Figure 2 is
not consistent with data in Table 1, the median specimen and lesion size in the Result section
are also not consistent with data in Table 2, etc.
2. You did not record the prevalence of OSA in your patients as mentioned in the Discussion.
However, the comorbidities of respiratory disease that you showed in Table 1 might confuse the
readers, as no obese patients suffered from respiratory disease. You may clarify the definition
or the entity of respiratory disorder that you have collected.
Sincerely yours,
Uayporn Kaosombatwattana
