Cumulative incidence of 1-year transplant-related mortality (TRM) in relation to NOD2/CARD15 SNPs. Wt indicates unmutated SNPs (wild-type) in both recipients and donors; mut: any mutated SNP in donor or recpient or in both. (A) HLA-identical sibling transplantations; wt: n = 55, mut: n = 23. (B) HLA-matched unrelated donor transplantations; wt: n = 61, mut: n = 25.
