OS and progression/relapse-free survival stratified by conditioning regimen. Probability of OS stratified by conditioning regime 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). Probability of PFS stratified by conditioning regimen in the European (C) and Japanese cohorts (D).
