Mammography Rates Among Intervention and Control Patients at Least 2 Years Overdue for Breast Cancer Screening

	Unadjusted rates				Adjusted rates*
	Intervention	Control	Difference (95% CI)	P-value	Difference (95% CI)	P-value
All patients	969/3,054 (31.7%)	857/3,676 (23.3%)	8.4% (6.3–10.6)	<0.001	8.1% (5.1–11.2)	<0.001
Physician-Connected	628/1,689 (37.2%)	566/2,002 (28.3%)	8.9% (5.9–11.9)	<0.001	8.0% (4.0–12.3)	<0.001
Practice-Connected	341/1,365 (25.0%)	291/1,674 (17.4%)	7.6% (4.7–10.5)	<0.001	8.1% (4.9–11.7)	0.01

^*Adjusted rates and p-values were obtained from multiple logistic regression models comparing intervention and control groups controlling for patient age, race/ethnicity, insurance status, English language proficiency, practice type (health center vs non-health center), and number of months since last practice visit using cluster analysis with generalized estimating equations methods. The “All Patients” model also adjusted for patient-provider connectedness. Models were adjusted to the covariate levels that produced the same adjusted and unadjusted rates in the control group.
