		“My Patient”	“Not My Patient”	P Value*	“My Patient”	“Not My Patient”	P Value*
Breast cancer, Mammography†	2,636 (82.7%)	1,917 (85.9%)	719 (74.4%)	.01	1,740 (87.9%)	896 (72.7%)	<.001
Cervical cancer, Pap Smear‡	8,242 (82.7%)	5,231 (83.8%)	3,011 (80.7%)	.77	4,356 (84.9%)	3,886 (80.2%)	.20

^*P-values comparing actual and predicted patient loyalty designation to the provider using multiple regression modeling controlling for individual provider cluster with general estimating equation methods

^†Mammogram performed over the prior 2 years in eligible women aged 52 to 69 years old

^‡Papanicolaou (Pap) smear performed over the prior 3 years in eligible women aged 18 to 65 years old

^§Colorectal cancer screening test performed in all patients aged 52 to 69 years old: colonoscopy in the prior 10 years; flexible sigmoidoscopy or double contrast barium enema in the prior 5 years; or fecal occult blood test in the prior year
