  1. * Relevant screening tests include fecal occult blood testing, flexible sigmoidoscopy, and colonoscopy.
  2. † A t-test for difference in means was used to compare age; all other variables were compared using Chi-Square and Fisher's Exact tests.
  3. ‡ Because some patients have more than one type of insurance, percentages add to greater than 100%.
