The association between inflammation and K7 expression in distinct sites of the lower gut.

The inflammatory activity, number of biopsies in each class, median percentage of K7( +) cells in sites of biopsy from ileum to rectum, and statistical significance of the difference (p-values) in K7 expression between normal and inflamed epithelial cells in terminal ileum and distinct sites of colon. *p < 0.05 was considered statistically significant.
