Cumulative incidence of TRM by nonpermissive or permissive DPB1 mismatches according to TCE-X or TCE-FD. Shown are probabilities of TRM for transplants stratified according to DPB1 nonpermissive or permissive mismatches by TCE-X (A) or TCE-FD (B). The numbers in each group were n = 1166, 1564, 1279, and 1451 for TCE-X nonpermissive, TCE-X permissive, TCE-FD nonpermissive, and TCE-FD permissive pairs, respectively.
