*Model 2: competing risk regression adjusted for age, sex, body mass index and smoking status with backward selection method.

†Model 3: Competing risk regression adjusted for age, sex, body mass index, smoking status, number of bypass grafts, left ventricular ejection fraction, diabetes mellitus, hypertension, chronic kidney disease and excessive daytime sleepiness with backward selection method.
