  1. aUsed student's t test to compare the age of the two groups. Categorical values compared with chi-square test (colorectal cancer, scattered ulcer/erosion, hemorrhoids), and Fisher's exact test was used when expected count of one set of samples was less than 5(ulcerative colitis, colon and rectum cancer, scattered ulcer/erosion of ascending colon, transverse colon and descending colon)
