Table 4.

Use of the MELD‐XI score together with the VALID‐CRT risk score improves the prediction of all‐cause mortality

Risk score	C‐statistics (95% CI)	P	NRI (95% CI)	P	IDI (95% CI)	P
VALID‐CRT risk score	0.61 (0.54–0.67)	Ref.
VALID‐CRT risk score + MELD‐XI score	0.63 (0.57–0.70)	0.16	0.31 (0.08–0.54)	0.007	0.015 (<0.001–0.03)	0.044

CI, confidence interval; IDI, integrated discrimination improvement; MELD‐XI, Model for End‐stage Liver Disease excluding the International normalized ratio; NRI, net reclassification improvement.
