Receiver Operating Characteristic Curve for Early Hospital Readmission Prediction Models with and without Frailty.
Note: AUC is the area under the receiver operating characteristic curve. The registry-based model with frailty had statistically significant improvement in EHR prediction (P=0.01). The P value was obtained from a chi-squared test of the difference in the AUC for the registry-based models with and without frailty.
