Reviewer's report:  
 
This man uscript reported that the etiology of peptic ulcers has changed from previous reports and 
EoGE have been increasing as a cause of peptic ulcers. However, the information in this paper 
was inadequate and major revise may be needed to accept this journal.  
 
1. Page 2 line27, Page 8 line 48, Page 9 line 18, Table 1, table 2; The comparison was 
performed to determine whether there was a significant difference between the five groups. 
However, since the analysis was only for a significant difference somewhere in the five groups, 
it was not clear which group had a significant difference. In order to accurately determine a 
significant difference, a significant difference test should be performed for each group, and data 
between groups having significant differences should be generated. For example, the comparison 
between the EoGE group and the other groups should be described as having a significant 
difference.  
 
2. Page 2 line 42, Page 12 line 29, Page 13 line 29; In the results, comparison was made 
between the EoGE group and the non -EoGE group. However, a reviewer could not understand 
that authors suddenly mentioned the numerical value in NHGN -PU in the conclusion. Authors 
should have unified with either.  
 
3. Page 4 line 51, Page 8 line 8; The definition of group A was not explicitly mentioned. 
The author should mention that the period during which patients was taking gastrotoxic drugs, 
the period from after taking i t to the endoscopic examination.  
 
4. Page 8 line 25, Figure; Authors noted that EoGE had been considered from 2011. 
However, because this study was a retrospective study, it was needed to reconfirm all 
pathological specimens from 2003 to 2010.
