Bold denotes probe sets that are used for building the regression tree model.

*

Indicates risk group with which elevated expression is correlated.

P value indicating significance of the association between the expression of each gene and treatment outcome adjusting for the MLL status.

P value indicating significance of the association between the expression of each gene and treatment outcome adjusting for age effect.

§

P value of Wald test for the HR indicating significance of the association between the expression of each individual gene and treatment outcome.
