Figure 1. Flowchart depicting the enrollment and analyses of the study population.
Figure 2. The distribution of sick sinus syndrome from the incident atrial fibrillation (AF). The red line indicates AF diagnosis.
Figure 3. The cumulative incidence of the sick sinus syndrome (SSS) before (A and B) and after censoring for stroke (C and D) in the overall population (A and C) and propensity score (PS)-matched population (B and D).
Figure 4. Hazard ratios (HR) for sick sinus syndrome (SSS) in different subgroups in the overall population. Boxes indicate the HR, limit lines indicate the 95% confidence interval (CI), and the horizontal line (at HR 1) indicates no difference in the HR between atrial fibrillation (AF) and no-AF.
