After PSM, the incidence density of dementia (HR, 1.57; 95% CI, 1.00–2.45; P = 0.0501) was higher with borderline significance in patients with AF than in patients with AFL, and the incidence density of ischemic stroke (HR, 2.54; 95% CI, 1.56–4.12; P = 0.0002) was significantly higher in patients with AF than in patients with AFL (Supplemental Table 5).
