Comparison of PFS, EFS, and OS between the nilotinib arm and the dasatinib arm. PFS (A), EFS (B), and OS (C). PFS, EFS, and OS were defined as the interval from the date of randomization until the date of progression or death from any causes, whichever came first (PFS); until the date of the earliest of defined events (EFS); and until the date of death from any causes (OS), respectively. PFS, EFS, and OS were analysis on the ITT population using the Kaplan-Meier method with a log-rank test.
