Relapse/progression and nonrelapse mortality stratified by the conditioning regimen. Cumulative incidence of relapse or disease progression stratified by conditioning regimen was grouped into 4 (TBI-RIC, TBI-MAC, non–TBI-RIC, and non–TBI-MAC) in the European cohort (A) and in the Japanese cohort (B). Cumulative incidence of non-relapse mortality stratified by conditioning regimen was grouped into 4 (TBI-RIC, TBI-MAC, non–TBI-RIC, and non–TBI-MAC) in the European cohort (C) and in the Japanese cohort (D).
