Figure 3 Event-Free Survival by CTA

Risk-adjusted event-free survival by computed tomography angiography (CTA)-diagnosed coronary artery disease (CAD) (left), and coronary artery calcium score (CACS) in the group with CTA-diagnosed nonobstructive CAD (right). Risk adjustment included the following variables: age, gender, hypertension, hypercholesterolemia, diabetes mellitus, smoking, family history of premature coronary heart disease (right), and CACS (left). The presence of CTA-diagnosed CAD increased the risk of all-cause mortality. In patients with CTA-diagnosed nonobstructive CAD, increasing CACS was associated with decreased survival.
