Reviewer's report:  
This study aimed to compare the performa nce of AIMS65, Glasgow -Blatchford (GBS) and 
Rockall scores (RS) in predicting the death risk among emergency -hospitalized patients with 
upper gastrointestinal bleeding (UGIB) in regional China. It is an interesting study, but some 
minor revisions are sugge sted. 
1. Please eliminate UGIH and use UGIB which was used more frequently in this manuscript.  
2. Page 6 line 42 Coffee ground vomiting => coffee ground vomiting (should use lowercase

3. Page 7 line 17 s (e.g., Ischemic heart disease, Diabetes mellitus, Congestive cardiac failure, 
Liver disease) => (e.g., ischemic heart disease, diabetes mellitus, congestive cardiac failure, 
liver disease) (should use lowercase letter rather than capital letter)  
4. Page 12 line 59 proton pump inhibitors, Page 14 line 1 proton pump inhibitors (PPIs) => The 
first time you use an abbreviation in the text, present both the spelled -out version and the short 
form. Therefore, PPIs should be described in Page 12 rather than Page 14.
