a. Hosmer-Lemeshow Χ2 = 8.28, p = 0.4068.
b. Hosmer-Lemeshow Χ2 = 10.9, p = 0.2074.
c. Hosmer-Lemeshow Χ2 = 12.25, p = 0.1404. Includes stool test, colonoscopy, flexible sigmoidoscopy, or barium enema x ray. Persons with screens by multiple modalities are counted only once.
d The data sources used affects the amount of screening information available for patients of a given practice. It is not an indicator of predicting screening. Instead, this variable is used to control for the fact that some practices had more complete data than others.

Note: Confidence intervals and p values have been adjusted using cluster variance estimators.
