Comparison of times to cytogenetic and molecular responses between the nilotinib arm and the dasatinib arm. Times to the first CCyR (A), MMR (B), MR^4.0 (C), and MR^4.5 (D). Times to cytogenetic and molecular responses were defined as the intervals from the date of first dose to the response events and analyzed on the PP population by the cumulative incidence method with a Gray test. If the patients died or were lost to follow-up without achieving the events, these patients were treated as censored cases at the date of death or the last follow-up.
