^*Therapies include statin, anti-platelet therapy, and/or ACEI/ARB.

Model 1 = Adjusted for age, gender, race/ethnicity

Model 2 = Model 1 + atherosclerotic risk factors (diabetes, hypertension, hyperlipidemia, smoking, and chronic kidney disease)

Model 3 = Model 2 + health insurance status, education level, and socioeconomic status (based on poverty-income ratio)
