Title: Effect of Different Working Periods on Missed Diagnosis of Colorectal Polyps in
Colonoscopy
Version: 2 Date: 15 Jul 2024
Reviewer's report:
The manuscript has improved significantly.
I only have  a few comments.
Overall I appreciate the willingness to include some point estimates. In my comments I was
aiming at the proportions, such as you report regarding  the experience level of the endoscopists,
and not as much the Chi2 or fishers exact test results. My request was for those instances where
it makes sense in the text.
1.  Page 3, line 3: colonoscopies is misspelled.
2. On page 3, line 6-7 you the authors state: "...aged 26–28 years, with an average age of (57.76
± 11.33) years". I would believe that the age of 26-28 is a mistake as this does not match the
average age.
3. page 3, line 13: gastroscopy is misspelled.
4. Page 6, line 18-19: I would suggest rephrasing: "There was no statistically significant effect
on the number of missed polyps by different working periods "
