				p-race interaction
Model 1: HR(95% CI)	1.73(1.08–2.79)	2.04(1.23–3.40)	1.02(0.53–1.95)	0.05
Model 2: HR(95% CI)	1.68(0.90–3.13)	2.09(1.98–4.43)	0.88(0.45–1.73)	0.10
Model 3: HR(95% CI)	1.74(0.94–3.20)	2.13(1.01–4.50)	0.93(0.49–1.80)	0.20

Model 1 adjusts for age and sex; Model 2 adjusts for covariates in Model 1 plus income, education, BMI, smoking, physical activity, alcohol use, and season; Models 3 adjusts for covariates in Model 2 plus CRP, diabetes, hypertension, and hypercholesterolemia. For results for the total population, models 1–3 are also adjusted for race.
