Title: An extended 36-week oral esomeprazole improved long-term recurrent peptic ulcer
bleeding in patients at high risk of rebleeding
Version: 2 Date: 02 Sep 2022
Reviewer's report:
This is an interesting study and it provides some important clinical information. However, I have
several comments about this article.
1. The competing risks regression model was used in this study. Please explain the reason
using this model in this article. Can you provide the results without performing competing risks
regression model?
2.  (I think this point is not very important.) It seems need another statistical packages for
performing competing risks regression. If you also used another software or statistical packages
(besides SPSS Statistics “20.0”) to perform competing risks regression, please listed that in the
article.
3. It is better to briefly describe the Rockall scores and ASA classification in the article. I think
many readers cannot understand the meaning or importance of this score or classification.
