Reviewer's report:  
 
1) Line 156 -159 contains repeated information, should be rephrased and needs language 
correction  
 
2) Sentence in line 212 is incomplete  
 
3) Spelling errors in line 228, 258, 279  
 
4) Sentences in line 278 -279, 281 -282 are incomplete, difficult to understand, need language 
correction  
 
5) Line 285 correctly: "with small sample size", delete "a"  
 
6) Line 293 -295: Contrary to the statement, stent cannot be considered effective in RBES, since 
no additional benefit was shown in the study, i.e., stents did not reduce the frequency of  
dilatation
