Version: 0 Date: 24 Jul 2019  
 
Reviewer: Mihnea Dragomir  
 
Reviewer's report:  
 
Soh et al design ed a logical prospective randomized study in which they show the advantages of 
polyp clipping in preventing bleeding after polypectomy.  
 
 
 
Minor remarks:  
 
1. Add the p -values in text when comparing the two groups of patients.  
 
2. Provide an explanation why  clipping did not reduce delayed bleeding after polypectomy.  
 
3. Add an additional limitation to your study: the paper would have benefited by adding a 
third arm in which you would have added an already accepted prophylactic measure, like 
epinephrine inje ctions.  
 
4. The reference list is scarce and some important studies regarding the topic are missing: 
PMID: 30483572, PMID: 19430833.
