Characteristics of the study population according to HLA genotype^a.

aFour different groups were included to represent homozygosity and heterozygosity for the AH8.1 haplotype (as defined by the presence of HLA-B*0801 and DRB1*0301), absence of this haplotype as well as homozygosity for other DRB1 haplotypes. There were no significant differences (all p>0.23) for any of the parameters when applying Kruskal-Wallis test for continuous and 2x4 chi square test for categorical parameters. bTransport time as defined by time from sampling to the freezer.
