Figure 3. Calibration for incident AF.

Figure 3.

Depicted are fitted calibration curves demonstrating the relationship between predicted event risk (x-axis) and observed cumulative event incidence (y-axis) for and age and sex (gray), CHARGE-AF (orange), ECG-AI (green), and CH-AI (purple). Perfect calibration is indicated by the hashed diagonal line, denoting perfect correspondence between predicted and observed risk. Curves were obtained using adaptive hazard regression30 relating predicted risk and observed event risk.
