Follow-up of recipients posttransplantation. (A) Survival rates of subnormothermically perfused fresh and warm ischemic (WI) livers, as well as the simple cold storage (SCS) control group and the nonperfused WI group. (B) Body weights are normalized to preoperative weights. Error bars = SD. *P < 0.05 between WI-SNMP and UW-Control groups. **P < 0.05 between WI-SNMP and both the Fresh-SNMP and UW-Control groups.
