Adjusted means ± SE of CAC (green circles) and AAC (white circles) (as ln [AS + 1]) according to median values of energy-adjusted self-reported total (dietary and supplemental) magnesium intake in quartile categories in 2,695 participants of the Framingham Heart Study. Highest versus lowest intake was associated with 34% lower CAC (p linear trend: <0.001), and 28% lower AAC (p linear trend: 0.02). Values are adjusted for age, sex, exam cycle, body mass index, smoking status, systolic blood pressure, fasting insulin, total–to–high-density lipoprotein cholesterol ratio, use of hormone replacement therapy (women only), menopausal status (women only), treatment for hyperlipidemia, hypertension or cardiovascular disease prevention, or diabetes, and intake of energy, calcium, alcohol, vitamins K and D, saturated fat, and fiber. AAC = abdominal aortic calcification; AS = Agatston score; CAC = coronary artery calcification.
