Adjusted calibration for deciles of observed (derived from Kaplan-Meier estimates, dark bars) and predicted (derived by risk function, gray bars) risk of 5-year incidence of atrial fibrillation for FHS (Figure 2a). For AGES and CHS we display 2 figures. The inset figure shows the unadjusted results, the larger figure is the recalibration accounting for different baseline prevalence of risk factors and incidence of AF. AGES (Figure 2b), CHS whites (Figure 2c) and AA (Figure 2d).
