(A) Kaplan and Meier’s plot of overall survival of all randomized patients, irrespective of any protocol violation and of the cause of death. The cases who were submitted to allogeneic BMT in chronic phase were censored at the date of transplant. Log-rank test,P = .002. The number of cases at risk at each year is shown below the graph. (B) Time from randomization to progression to accelerated or blastic phase. The cases who were submitted to allogeneic BMT in chronic phase and the cases who died in chronic phase were censored. Log-rank test, P = .0005.
