Correlation of oncogene overexpression to 11q23 copy number status. The geometric averages of the normalized expression of MLL, DDX6, FLI1, PLZF, CBL, and ETS1 in the different patient groups (“Results”); group A (▪), group B (▦), and group C (□). P values indicate the significance of the difference in observed expression in 2 by 2 analyses of the different patient groups, as identified by the Mann-Whitney test. Significant P values are indicated in bold.
