Kaplan–Meier survival curve for major adverse cardiac events (MACE): a trend towards superior survival in patients without signs of coronary artery disease (CAD; 0%) as compared to CAD+ groups; with a close-to-borderline statistical significance level (p=0.063), and declining survival probability with increasing stenosis severity.
