CAC score ratio ¹ (95% CI) by ECG risk score in 134,802 study participants.

CAC Score	ECG Risk Score				p- Value
	0	1	2	≥3
Age- and sex-adjusted CAC score ratio (95% CI)	1.0 (reference)	1.03 (1.02–1.04)	1.22 (1.20–1.34)	1.21 (1.18–1.25)	<0.001
Multivariate-adjusted CAC score ratio (95% CI)	1.0 (reference)	1.01 (1.00–1.03)	1.13 (1.10–1.16)	1.23 (1.16–1.31)	<0.001

¹ Estimated from Tobit regression models using natural log (CAC + 1) as the outcome. The multivariate-adjusted model was adjusted for age, sex, center, year of screening, BMI, smoking status, alcohol intake, physical activity, education, history of diabetes, history of hypertension, family history of heart disease, HDL-C, LDL-C, and triglyceride level. Abbreviations: BMI, body mass index; CAC, coronary artery calcium; CI, confidence interval; ECG, electrocardiogram; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol.
