Landmark analysis at 6 months of the impact of HSCT in CR1. Kaplan-Meier estimates for OS from a 6-month landmark of the 268 HSCT candidates and 261 chemotherapy-only candidates still alive at 6 months from inclusion (96.4% and 97.8% of the total HSCT and chemotherapy-only candidates, respectively; Figure 3) transplanted (N = 132 HSCT candidates, N = 69 chemotherapy-only candidates) or not transplanted (N = 136 HSCT candidates, N = 192 chemotherapy-only candidates) before the 6-month landmark. P values from log-rank tests and from the interaction term of a bivariate Cox model.
