Table 2

Donor-related factors.

	Foreign group ()	Domestic group ()	value
Mean age (years)	66.3 ± 8.7	27.8 ± 11.3	=0.000
DPT (hours)	6.3 ± 2.2	10.4 ± 5.3	=0.001
POT (hours)	125.4 ± 36.7	23.6 ± 8.9	=0.000
ECD (cell/mm^2)	2204 ± 242	3048 ± 277	=0.000

DPT: death-to-preservation time; POT: preservation-to-operation time; ECD: endothelial cell density.
