a. Hosmer-Lemeshow Χ2 = 24.69, p = 0.002.
b. Hosmer-Lemeshow Χ2 = 14.33, p = 0.074.
c Hosmer-Lemeshow Χ2 = 13.38, p = 0.099. 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.
