intermediate <strong>and</strong> long CR1 times, FAB 1 or 2 was a risk factor for death. The<br />

opposite was true for patients with short CR1 times. There was apparently an effect<br />

of CR1 time on the risk of death due to an extra chromosome 8. However, because<br />

of model fitting problems, it is not possible to describe the interaction between<br />

those factors.<br />

When CR1 time was forced into the DFS model, FAB 1,2 vs. others (P=0.045),<br />

MDS or secondary AML (P=0.017), <strong>and</strong> PM81 (P=0.025) were associated with<br />

risk of death or relapse. As shown in Table 8, MDS or secondary AML was<br />

strongly associated with increased risk of death or relapse. There was interaction<br />

between the other two factors <strong>and</strong> time in CR1, although the relationship between<br />

PM81 <strong>and</strong> DFS was obscured by model fitting problems. FAB 1 or 2 patients with<br />

short CR1 times (
