	White   (n = 9,570; 1,171 Events)		Black   (n = 3,029; 537 Events)
Model	HR	95% CI	HR	95% CI
Model 1b	0.83	0.77, 0.88	0.77	0.70, 0.85
Model 2c	0.86	0.81, 0.92	0.79	0.71, 0.87

Abbreviations: CI, confidence interval; HR, hazard ratio.

^a Pooled standard deviation = 2.80.

^b Model 1: adjusted for age, sex, and apolipoprotein E 4 allele status.

^c Model 2: model 1 with the addition of body mass index, hypertension, diabetes, high-density lipoprotein cholesterol, total cholesterol, alcohol-drinking status, and tobacco-smoking status.
