DFS from CR according to donor availability in 4 cytogenetic groups. The cytogenetic groups were good risk (A), intermediate risk (B), bad/very bad risk (C), and unknown (D). The estimates of the 4-year DFS rates (± SE) for the donor group (dotted line) and the no donor group (solid line) are given. The 4-year cumulative incidences of relapse and of death in CR are given in italics. N indicates number of patients; O, observed number of events (relapse or death in first CR). P was determined by the log-rank test.
