Cumulative incidence of leukemic relapse according to the expression of CKS1B, FLJ20105, BUB3, and H2AFZ, as detected by probe sets 219650_at, 201897_s_at, 201457_x_at, and 200853_at on the Affymetrix 133A gene chip, respectively. Solid lines represent patients with low gene expression and dashed lines those with expression at or above the median value; 10-year cumulative incidence of relapse (± SD) is indicated. In a multivariate analysis, each of these genes was a stronger predictor of leukemic relapse than any competing covariate included in the model.
