Reviewer's report:  
 
Dear authors,  
 
 
 
Thank you for answering my questions in detail and fo r implementing my recommendations 
where you saw fit. I will respond to some, but not all the alterations you made, as overall I agree 
they are interesting additions.  
 
 
9. Thank you for addressing this issue in your discussion. You presented the point very clearly in 
lines 509 -514. My advice would therefore be to leave out lines 514 -520. 
 
 
11. I would advise to shorten the discussion to improve readability. This can be don e in my view 
by omitting lines 451 -461, summarizing lines 478 -483 and maybe shortening the explanation of 
the designs of the three recent RCTs. Here, it is enough in my opinion to highlight parts that are 
interesting to compare with your own findings (e.g.  lesion size, complete closure, your idea that 
clip experience is important etc.). Also, I think you have already discussed lines 561 -564 
adequately in 544 -546, and may therefore leave them out.  
 
 
One final correction: you write that Pohl's article was publ ished after Albeniz's, but this is 
actually the other way around.  
 
 
 
Kind regards
