Discrimination, Accuracy and Validation of Models in Predicting Injurious Falls

	Results of 5-Fold Cross-Validation
	AUROC				C-Index	Brier Score
Model	6 months	12 months	18 months	24 months	Overall	Overall
MELD-Na	0.51	0.56	0.57	0.56	0.54	0.12
ICT weighted lures	0.53	0.54	0.53	0.53	0.53	0.12
Chair-stands and hand-grip	0.72	0.75	0.74	0.71	0.69	0.11
SF-8 and Sodium	0.71	0.76	0.75	0.70	0.69	0.11
FallSSS Score	0.79	0.81	0.80	0.76	0.74	0.11

AUROC (area under the receiver operating characteristic curve), ICT (inhibitory control test), MELD-Na (Model for Endstage Liver Disease-Sodium), SF-8 (Short-form 8), and FallSSS score (Prior Falls, serum Sodium, SF-8, and number of chair-Stands performed within 30 seconds). AUROC and c-indices lack confidence intervals as they the product of cross-validations.
