Description of Colonoscopy vs Fecal Immunochemical Test in Reducing Mortality From Colorectal Cancer Study Participants
COLORECTAL CANCER
Abbreviations: BMI, body mass index (calculated as weight in kilograms divided by height in meters squared); CRC, colorectal cancer; FIT, fecal immunochemical testing.Percentages for each variable may not sum to 100% because of refusal or missing data.No breakdown of the races and ethnicities that made up the other category was available.Spanish, Hispanic, or Latino.Percentage calculated with the denominator of ever-smokers.Other characteristics of the population included a mean (SD) body mass index (as measured by weight in kilograms divided by height in meters squared) of 30.2 (5.9). Most of the participants reported having at least some post–high school education (35 824 [71.5%]). Some history of smoking was common (31 474 [62.8%]), with current smoking reported by 12 682 (40.3%).Aspirin use was reported by 20 666 participants (41.2%), while statin use was reported by 19 565 (39.0%). Among the 3507 participants who completed the dedicated baseline survey for women, 230 (6.6%) reported current hormone replacement therapy. As would be expected in a randomized study of this size, characteristics were well balanced between the 2 intervention groups.
