Eosinophil counts in each part of the gastrointestinal tract in normal controls, children with functional abdominal pain disorders (FAPDs), and children with inflammatory bowel diseases (IBD). The order of bar graphs is normal controls, FAPDs, and IBD. In the rectum, eosinophil counts according to both upper gastrointestinal (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.
