Title: Nomogram for predicting rebleeding after initial endoscopic epinephrine injection
monotherapy hemostasis in patients with peptic ulcer bleeding: a retrospective cohort study
Version: 1 Date: 16 Jun 2022
Reviewer's report:
As the authors have stated, EI monotherapy tends to be widely used among patients because of
its accessibility and low expenditure, especially in nontertiary hospitals.
This study is very useful for the differentiation of high-risk patients with acute bleeding, which
is essential for postoperative surveillance.
However, the risk assessment of the patient should not influence the choice of the method of
endoscopic treatment of PUB, and whenever possible  and when indicated combination therapy
should be used regardless of the patient's risk and his general condition.
After bleeding control by EI, the method of definitive hemostasis such as thermal, mechanical or
sclerosant injection should  be used if is possible ( depending on the availability of the method,
familiarity with the method, the skill of the operator).
I think the authors should emphasize this more clearly in the discussion and conclusion
