CAC=coronary artery calcium; CHD risk factors: age, history of smoking, hypertension, waist-hip ratio (every 0.2 units), HOMA-IR (log) and total cholesterol/high density lipoprotein cholesterol ratio: OR=odds ratio. 95% CI=95% confidence interval

Addition of race, menopausal status, family history of CHD, homocysteine, current aspirin use, lipid-lowering medication or hydroxychloroquine use did not change the multivariate model.
