Lp(a)-related risk of carotid plaque at baseline^* was assessed in 5,155 Multi-Ethnic Study of Atherosclerosis participants stratified by race/ethnicity.

	Black N=1393	Caucasian N=1986	Chinese American N=620	Hispanic N=1156
per Lp(a) log unit	1.02 (0.80 − 1.07)	1.05 (1.03 − 1.08) <0.001	1.06 (0.97 − 1.16)	1.04 (0.99 − 1.09) 0.10
Lp(a)≥ 30 mg/dL	1.03 (0.94 − 1.13)	1.16 (1.09 − 1.24)† <0.001	1.14 (0.91 − 1.41)	1.12 (0.99 − 1.26) 0.07
Lp(a)≥ 50 mg/dL	1.05 (0.96 − 1.15)	1.20 (1.12 − 1.28)† <0.001	1.10 (0.82 − 1.47)	1.13 (0.98 − 1.30) 0.11

Risk ratios and 95% confidence intervals are shown, p-values where significant or approaching significance. Covariate adjustments were made for age, sex, systolic blood pressure, hypertension and lipid lowering medication use, total cholesterol, HDL-C, diabetes, and smoking status. Race-interactions were tested between racial/ethnic groups. Individuals with missing covariate data were excluded. Definitions: Lp(a)=lipoprotein(a); diabetes=treated and untreated cases; HDL-C=high density lipoprotein-cholesterol; smoking status=current, former, never
