Reviewer ’s report  
 
Title: Circular stripes were more common in Barrett's esophagus after acetic acid staining  
 
Version: 0 Date: 07 Dec 2017  
 
Reviewer: Stefano Brignola  
 
Reviewer's report:  
 
The article is of interest and wel l written and organised but i have some minor concern:  
 
- at line 96 there is a repetition of the AA's preparation which has already been illustrated at line 
90; 
 
 
- in the discussion section is reported data about correlation between grastroesophageal reflux  
and symptoms, but these data are not present in the results or methods sections; I suggest to 
include these data in table 1.
