Genome-wide recipient mismatching appears to have limited effects on the risks of GVHD-related outcomes. HRs (diamonds) and 95% CIs (lines) show GVHD-related outcomes per 0.01 increment of genome-wide recipient mismatching for coding SNPs among (A) sibling recipients and (B) unrelated recipients, adjusted for HLA-DPB1 T-cell epitope matching. Recipient mismatching was counted as described in Figure 1. Results were similar when recipient mismatching was counted as 0, 1, or 2 for each SNP, corresponding to no mismatching, mismatching for a single allele, or mismatching for both alleles, respectively.
