Kaplan-Meier curves: revascularisation rate (PCI or CABG) was significantly higher (p<0.0001) in the CAD+ group (without a statistical difference among stenosis severity groups). Kaplan-Meier curves: revascularisation rate (PCI or CABG) was significantly higher (p<0.0001) in the CAD+ group (without a statistical difference among stenosis severity groups). CAD+, positive for coronary artery disease; PCI, percutaneous coronary intervention; CABG, coronary artery bypass grafting. Fabian Plank et al.
