AUC and Sensitivity of the Gradient Boosting Machine model, Charlson Comorbidity Index (CCI), and Length of Stay
Model | AUC (95% CI) | Sensitivity at 20% FPR (95%CI) | Sensitivity at 30% FPR (95% CI) |
---|---|---|---|
Gradient boosting machine | 0.70 (0.68–0.72) | 0.45 (0.42–0.48) | 0.58 (0.55–0.61) |
Charlson comorbidity index | 0.59 (0.57–0.60) | 0.29 (0.27–0.31) | 0.43 (0.40–0.45) |
Length of stay | 0.58 (0.56–0.60) | 0.31 (0.29–0.39) | 0.47 (0.44–0.49) |
Abbreviations: AUC, area under receiver operator curve, FPR, false-positive rate.
