Reviewer's report:
Thank you for the opportunity to read this very valuable study.
I am very interested in novel scoring models for upper gastrointestinal bleeding.
I would like to confirm a few points, which are listed below.
Major comments
1. Your study included patients who underwent esophagogastroduodenoscopy within 6 hours.
Is there a rationale for setting the time frame at 6 hours? With reference to previous reports,
what is your opinion that 12 or 24 hours would be a better study design for this study to be
more generalizable?
2. Do you think the above new score model is versatile, not only for high-volume centers?
