In this largest national series of DCD HT procurement perfusion strategies, NRP is associated with improved short-term survival as compared with DPP.

As reported in the abstract
- Unadjusted Kaplan-Meier: improved short-term survival with NRP
- log-rank P = 0.005
- Propensity-matched analysis: cumulative survival benefit to NRP
- log-rank P = 0.006
