Predictive discrimination of waitlist (WL) mortality and transplant rate models. We tested the predictive discrimination of competing risks (WL mortality) and Poisson (transplant rate) models to quantify if addition of the Fried frailty phenotype, the short physical performance battery (SPPB), or both (Frailty +SPPB) improved the discrimination of the baseline adjusted model.

	WL Mortality		Transplant rate
	C Statistic	p value	C Statistic	p value
None	0.64	REF	0.63	REF
Frailty	0.68	<0.001	0.65	0.001
SPPB	0.68	<0.001	0.66	<0.001
SPPB + Frailty	0.68	<0.001	0.66	<0.001

None refers to the c-statistic in the adjusted model without frailty or SPPB.
