Table 1 Risk classification for donation after cardio-circulatory death donors and donation after cardio-circulatory death-liver transplantations recipients

Authors		Donors	Recipients
Mateo et al[74]	Low risk	Both WIT ≤ 30 min and CIT ≤ 10 h	RCRR ≤ 1.5
	High risk	WIT > 30 min and/or CIT > 10 h	RCRR > 1.5
			Re-transplantation and/or
			On life-support and/or
			A combination of ≥ 3 risk factors:
			Hospitalization or in an intensive care unit
			Serum creatinine > 2 mg/dL
			On dialysis
			Age > 60 yr
Lee et al[32]	Low risk	Donors with no identified donor risk factors	Recipients with no identified recipient risk factors
	High risk	Donors with at least one identified donor risk factor:	Recipients with at least one identified recipient risk factor:
		Donor age > 45 yr	Previous transplantation
		WIT > 15 min	Life support at transplantation
		CIT > 10 h
de Vera et al[34]	Low risk	-	MELD scores ≤ 30
	High risk	-	MELD scores > 30
			On life support (mechanical ventilation, hemodialysis)

RCRR: Recipient cumulative relative risk; WIT: Warm ischemia time; CIT: Cold ischemic time; MELD: Model for end-stage liver disease.
