Eosinophil counts in each part of the gastrointestinal (GI) tract in normal controls, childrens with functional abdominal pain disorders (FAPDs), and children with inflammatory bowel diseases (IBD) after eliminating the GI segments with grossly affected IBD lesion on endoscopy. The order of bar graphs is normal controls, FAPDs, and IBD. In the rectum, eosinophil counts according to both upper GI reference and lower GI reference were presented because lower GI tract pathology reference presented the “rectosigmoid area,” with no clear division between the sigmoid and the rectum. *P-value is less than 0.05. HPF, high-power field; A-colon, ascending colon; T-colon, transverse colon; D-colon, descending colon; S-colon, sigmoid colon.
