Linear Regression for FPC Satisfaction after Stratifying for Amount of Annual Usage

Variable	All Patients		Low Usage (n = 47)		Mid Usage (n = 87)		High Usage (n = 52)
Variable	β	P	β	P	β	P	β	P
Continuity	1.21	.001	1.03	.10	1.23	.002	2.15	.02
Ease of appointment	0.17	<.001	0.18	.04	0.16	.006	0.15	.16
PCP satisfaction	0.23	.002	0.28	.07	0.19	.05	0.56	.007
Active duty (1)/Retired (0)	−0.75	.001	−0.40	.39	−0.46	.14	−1.77	<.001

Outcome variable=Global FPC Satisfaction (on 10 point scale); R² for all patients=0.295; R² for low usage=0.335; R² for mid usage=0.302; R² for high usage=0.421.
