Reviewer: HJ Van Kruiningen  
 
Reviewer's report:  
 
Please include all comments for the authors in this box. The  authors have gone to extremes to 
quantify things that are subjective or that vary from one section to the next, such as numbers of 
these cells vs those cells, intra -epithelial neutrophils, basal plasmacytosis, crypt abnormality, 
goblet cells etc. Further,  they have not acknowledged that Crohn's disease is a submucosal  and 
intramuscular disease. Overly quantifying cells of the mucosa and aggregates of them is not 
helpful; cuts of resection specimens would be much more relevant, but also impossible to 
quant itate.  Suspected CD is also too subjective. You need to study clearly defined CD, 
established by several methods, and forget about suspected material.  To give statistical 
significance to "uneven inflammation" is the epitome of subjectivity; foolish.
