Title: Long-term outcomes of refractory esophageal strictures after endoscopic submucosal
dissection of superficial esophageal neoplasms
Version: 5 Date: 05 Feb 2022
Reviewer's report:
General comments:
The manuscript was well revised, however it requires some minor revisions yet. Please provide
further attention as described below.
Minor and specific comments:
1. “Refractory esophageal strictures (RESs)” was described at the second time at
BACKGROUND section, line 83, page 4. Please describe the abbreviation (RESs) only at this
point.
2. The authors described that “Propensity score matching was used to minimize lesion size bias.”
at line 265-266, page 10. What factors were used as adjustment factors to create the propensity
score? Please add the description at “Statistical analysis” section. Furthermore, how many cases
were there at each group after matching? Please provide the detail before and after matching.
