CCTA findings
 Maximal stenosis severity (per grade) 2.24 1.61–3.10 <0.001
 Number of vessels with obstructive CAD 2.30 1.75–3.03 <0.001

Adverse events include all-cause mortality, non-fatal myocardial infarction, and late (≥90-day) target vessel revascularization. Obstructive CAD is defined as a ≥50% stenosis. Maximal stenosis severity is graded as 0, 1–49%, 50–69%, and ≥70% diameter luminal stenosis. CACS = coronary artery calcium score, CAD = coronary artery disease, CCTA = coronary computed tomographic angiography, CI = confidence interval, HR = hazard ratio.
