Performance characteristics for short‐term death prediction of scores A_d, A_i, B_d and B_i on training cohort

Score	Optimal cutoff	Sensitivity (%)	Specificity (%)	Youden index	AUC	95% CI for AUC
Ad	10.0	89	90	0.79	0.92	0.85‐0.99
Ai	11	89	90	0.79	0.92	0.85‐0.99
Bd	5.4	96	77	0.73	0.92	0.85‐0.99
Bi	6	96	77	0.73	0.92	0.85‐0.99

Score A_d, from model A with weighting factors rounded after the decimal point.

Score A_i, from model A with weighting factors rounded to the closest integer.

Score B_d, from model B with weighting factors rounded after the decimal point.

Score B_i from model B with weighting factors rounded to the closest integer.

Abbreviations: AUC, area under the ROC curve; CI, Confidence Interval.
