Comparing the predictability model using ROC curve.

Predictability model	AUC	Standard error	95% CI	p value
Model 1  Previous or current smoker  High TG (⩾1.7 mmol/L)  High ICAM-1 (⩾347.48 ng/mL)	0.648	0.049	0.552–0.743	0.003
Model 2  Previous or current smoker  High TG (⩾1.7 mmol/L)	0.610	0.050	0.512–0.707	0.041

ROC: receiver operating characteristic; AUC: area under the curve; CI: confidence interval; TG: triglyceride; ICAM-1: intercellular adhesion molecule-1.
