Discrimination: This risk calculator sorts patients who died earlier from patients who were still alive correctly 76% of the time (as measured by the integrated area under the receiver operating characteristic curve (iAUC) which is a weighted average of the AUC values at all event times). The time-specific AUC values after bootstrap internal validation in the HRS cohort were 0.73 at 1 year, 0.73 at 2 years, 0.75 at 5 years, and 0.84 at 10 years. Upon external validation in NHATS, the time-specific AUC values were 0.73 at 1 year, 0.73 at 2 years, and 0.74 at 5 years.
Calibration: Calibration plots suggested good calibration across the range of predicted risk in both the HRS and NHATS cohorts.
