Kaplan–Meier event-free survival curves and comparisons between patients with or without dementia by log-rank test in all patients (N = 10,171). a The incidence of MACCE was significantly higher in patients with dementia than in those without dementia (P < 0.001). b Patients without dementia showed better survival rate than patients with dementia (P < 0.001). c-e There were no significant differences in event-free survival rates of nonfatal acute myocardial infarction, target vessel revascularization, or nonfatal hemorrhagic stroke (P = 0.725, P = 0.236, and P = 0.409, respectively). f However, incidence of nonfatal ischemic stroke was significantly higher in patients with dementia than in those without dementia (P < 0.001).
