Impact of extended criteria donor transplants on infections in kidney and liver transplant recipients and marginal donor definition criteria: a systematic review

Abstract Background Expanded criteria donors (ECDs) have become an important source of organs, but their association with infection risk remains unclear. This systematic review assessed the impact of ECD versus standard criteria donors (SCD) on infection rates in kidney and liver transplant recipients and analysed the variability of ECD definitions.
