Relapse-free interval (cumulative incidence of relapse as first event) according to the 3 randomization arms. Panel A shows relapse-free interval in the 449 CR patients (P = .39 and .15 when arms B and C were compared to arm A, respectively, using the Gray test) (Table 3); and panel B, in the 282 CR patients younger than 50 (P = .26 and .038 when arms B and C were compared to arm A, respectively, using the Gray test) (Table 5).
