↵* Adjusted rates and P values obtained from mixed effects models comparing intervention and control groups controlling for patient age, ethnicity, insurance status, primary language, time since last visit to practice, patient–physician linkage, and sex (for colorectal cancer and all screenings combined) while accounting for clustering by primary care physician or practice in a mixed effects model.
