Multivariable Cox regression model for one-year post-transplant mortality, adjusted for region as well as donor, recipient, and transplant parameters.

	MELD ≥ 35	MELD < 35
	HR (95% CI)	HR (95% CI)
Share 35	0.69 (0.60–0.80)	0.98 (0.89–1.07)
Recipient condition at time of transplant (Ref: Not hospitalized)
Hospitalized in ICU	1.80 (1.40–2.30)	2.23 (1.85–2.68)
Hospitalized, not in ICU	1.18 (0.92–1.51)	1.36 (1.19–1.54)
Prior liver transplantation	1.62 (1.27–2.06)	1.95 (1.58–2.42)
Recipient age (per 10-year increase)	1.21 (1.13–1.29)	1.28 (1.21–1.35)
BiochemicalMELD at LT (per 5-unit increase)	1.00 (0.95–1.06)	1.09 (1.04–1.13)
Donor age (per 10-year increase)	1.08 (1.02–1.14)	1.05 (1.02–1.09)
DCD liver	1.78 (1.24–2.55)	1.32 (1.10–1.58)
Cold ischemia time (per 1 hour)	1.02 (1.00–1.05)	1.03 (1.02–1.05)
