cRF, calculated reaction frequency; DBD, donation after brain death; DCD, donation after circulatory death; HLA, Human Leucocyte Antigen.
HLA mismatch level (levels 1‐4) was defined according to the UK allocation policy for kidneys from brain‐death donors and was based on the mismatch between donor and recipient.14
aMissing data were <1% gender and HLA Mismacth level ethnicity and recipient sex and <2% for cold ischaemic time, 37% for warm ischaemic time.
