Ethnic Differences in Poor Appointment-Keeping Behavior, Risk Ratios (RR) (95% CI) from Modified Poisson Regression Models

Ethnicity	Model 1 RR (95% CI)	Model 2 RR (95% CI)	Model 3 RR (95% CI)	p-Value from Model 3
Caucasian (ref)	1.0	1.0	1.0	Reference
African American	1.7 (1.4, 2.1)	1.6 (1.4, 2.0)	1.6 (1.3, 1.9)	<.0001
Asian	0.8 (0.6, 1.1)	0.8 (0.6, 1.1)	0.7 (0.5, 1.0)	.05
Filipino	1.3 (1.0, 1.6)	1.1 (0.9, 1.4)	1.1 (0.8, 1.4)	.73
Latino	2.1 (1.8, 2.6)	1.8 (1.5, 2.2)	1.5 (1.2, 1.9)	.0001

Note: Model 1 includes ethnicity only; Model 2 includes ethnicity, age, and gender; Model 3 includes ethnicity, age, gender, education, income, assets, social support, depression, employment, limited English proficiency, health literacy, having an assigned PCP, trust-in-provider, medical center, age of diabetes onset, DxcG risk score, and competing demands. All models included missing indicators for the explanatory variables and were weighted to account for design effects and survey nonresponse bias.
