  1. *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.
  2. Because some patients have more than one type of insurance, percentages add to greater than 100%; p-value is for test of any insurance vs. no insurance
  3. Current screening defined as receiving fecal occult blood testing within the last year, flexible sigmoidoscopy within the last five years, or colonoscopy within the last 10 years.
