Subgroup analyses of OS in each group of the conditioning regimen. Superiority in OS of HDCA/CY/TBI (shown in Table 2) was analyzed in detail by each subgroup with respect to patient characteristics. Compared with the CY/TBI group, the unadjusted HRs of overall mortality in the HDCA/CY/TBI group were significantly lower than 1 (ie, HDCA/CY/TBI is prognostically advantageous) in almost all the subgroups. HRs are shown by black dots, and 95% CI ranges are indicated by black bars.
