a
Adjusted percentages presented as predictive margins from multivariate logistic regression models (adjusted for all other characteristics in Table 2).
b
P values are based on an overall Wald F test for association from multivariate logistic regression models.
c
American Indians/Alaska natives could not be included in the sigmoidoscopy model due to insufficient numbers.
