Risk scores for allograft failure: Are they still useful in liver recipients from donation after circulatory death?

Table 1 Correlation of overall and graft survival according to the United Kingdom risk score, subdivided by high-risk subgroups

Survival	Donors aged ≥ 70 years			Cold ischemia time ≥ 6 h				Functional warm ischemia time ≥ 12 min
	Low risk, n = 5	High risk, n = 7	P value	Low risk, n = 6	High risk, n = 4	Futile, n = 3	P value	Low risk, n = 24	High risk, n = 18	Futile, n = 4	P value
Graft survival in days	420 (306-1636)	236 (1-395)	0.0481	987 (11-1657)	592 (47-1480)	2 (1-3)	0.3302	505 (179-1469)	357 (1.2-1134)	218 (100-685)	0.3402
Overall survival in months	13 (9-53)	7 (1-12)	0.0881	32 (3.7-53)	19 (1.5-47.7)	8 (6-9)	0.8472	16 (5-48)	15 (8-36)	7 (2.7-22)	0.6782

Data are median (interquartile range).
