Atherosclerotic cardiovascular disease events predicted via the American Heart Association-American College of Cardiology-Atherosclerotic Cardiovascular Disease risk score and atherosclerotic cardiovascular disease events observed among Multi-Ethnic Study of Atherosclerosis participants aged 45–79, not taking lipid-lowering medication at baseline with low-density lipoprotein cholesterol between 70 and 189 mg/dL stratified by gender and race/ethnicity, including non-adjudicated Centers for Medicare & Medicaid Services myocardial infarctions
