Extended Data Fig. 1: Model performance (AUC) of the original VA model at each VA hospital.
From: Generalizability of an acute kidney injury prediction model across health systems
Model performance of the original model at each VA hospital in the test set, along with characteristics of each VA hospital. A. Model performance with respect to area under the curve (AUC) with 95% CI of the original VA model for predicting AKI-1+ at each VA hospital. The center dot represents the AUC when the original model is applied to the hospital, and the 95% CI is calculated by the DeLong’s method24. B. Number of predictions (after excluding those with AKI-1+ at baseline) at each VA hospital. C. Hospitalization-level AKI-1+ incidence in the test set (after excluding those with AKI-1+ at baseline) at each VA hospital. Five VA hospitals are not shown here due to small cohort sizes (<30 patients).
