Primary

MeasureTime frameDescription
The rate of young endurance runners' that have adenomatous polyps.36 months1. Estimate the rate of young endurance runners that have adenomatous polyps. 2. Estimate the rate of young endurance runners that have advanced adenoma and colorectal cancer on screening colonoscopies.

Secondary

MeasureTime frameDescription
Comparison of the rate of young endurance athletes that have adenomatous polyps with that of the historical controls (those in the average risk group).36 monthsFisher's Exact test will be used to compare the rates of adenomatous polyps and colorectal cancer between the young endurance athletes and that of the historical controls. 2.3 Secondary Objectives 1.
