Overall survival. (A) Kaplan-Meier estimates of OS from the time of randomization for patients who were randomized to the lestaurtinib arm compared with the control arm. Patients who received an allogeneic transplant were censored at the date of the allogeneic transplantation. (B) OS by duration of first remission. Kaplan-Meier estimates of OS from the time of randomization for patients whose first remission lasted from 1 to 6 months, and for patients whose first remission lasted more than 6 months. Patients who received an allogeneic transplant were censored at the date of the allogeneic transplantation.
