FOBT, fecal occult blood test; CI, confidence interval;

Mammography in past 2 years, women age > 39 home FOBT, adult workers in past year, age > 49 screening endoscopy, adult workers within past 5 years for flexible sigmoidoscopy or 10 years for colonoscopy.

*PM, predicted marginals from multivariate logistic models including all variables in Table 3.

p** values are based on an overall Wald F Chi Square test for association from multivariate logistic regression models.

*** relative standard error is greater than 30%, interpret estimate with caution.
