Abbreviation: RCC, reclassification calibration.

In the kth cell, n_k is the number of subjects, ${\hat{p}}_{k}$ is the observed event rate, ${\bar{r}}_{k}$ (baseline) is the average baseline model risk, and ${\bar{r}}_{k}$ (enhanced) is the average enhanced model risk ${\hat{p}}_{k}$ . ${\bar{r}}_{k}$ (baseline) and ${\bar{r}}_{k}$ (enhanced) are shown as percentages.
