bowel bleeding: A retr ospective study

Reviewer's report:  
 
First of all, I should mention that this article is a revised article. However, the original version of 
this article was not seen and evaluated by me.  
 
Secondly, when I look at the photos in figure 1B, 1C, 1D and 1E it is not poss ible to say whether 
any of these images are not compatible with Crohn's disease. Therefore, it is not possible to 
classify these lesions (1D and 1E) as NSAID -related ulcers only by looking at these images and 
the patient's history of aspirin / NSAID use.  
 
Thirdly, If you are going to give the percentage of a lesion or disease, you give the percentage 
according to the entire (whole) group, not just the group with positive findings: ie 25 of 60 is 
wrong.  
 
As a result, more detailed evaluation of capsule endosco pies of these patients is required. I think 
that without long term clinical follow -up, or capsule endoscopy repetttion after NSAID 
discontinuation, or histopathological evaluation it is not possible to classify these lesions as 
NSAID related lesions.
