Predictive value of TCE3 and TCE4 for OS after unrelated HSCT, stratified according to matching status at other HLA loci. Shown are Kaplan-Meier estimates of survival after HLA-DPB1 allele-mismatched transplantations, matched for 10 of 10 (A; n = 201), 9 of 10 (B; n = 199), or less than or equal to 8 of 10 (C; n = 137) of the alleles at HLA loci A, B, C, DRB1, and DQB1. (Left panels) Transplantations were stratified according to the presence of TCE3-permissive (solid lines) or nonpermissive (dashed lines) HLA-DPB1 mismatches. (Middle panels) TCE3-permissive transplantations were further subdivided into those permissive also according to TCE4 (—) and those nonpermissive according to TCE4 (). (Right panels) Transplantations were stratified according to the presence of TCE4-permissive (—) or TCE4-nonpermissive () HLA-DPB1 mismatches.
