^bP < 0.01 vs baseline in patients without colonic cancer;

^cP < 0.05 vs baseline in patients without colonic polyps;

^eP < 0.05 vs IBS but not other FBD groups; no differences in the incidence of colonic cancer or polyps were found between genders and places of residence and no differences in the incidence of colonic polyps were found among FBD groups (all P > 0.05). FBD: Functional bowel disorder; IBS: Irritable bowel syndrome.
