Survival plots for patients with high and low IGSF4 expression. Plots showing overall survival (pOS) (A), EFS (pEFS) (B), and cumulative incidence of relapse (CIR; C) for all MLL-rearranged patients (n = 26 [IGSF4 high] vs n = 53 [IGSF4 low]). Median expression in the t(9;11) group was chosen as a cut-off for the division in high and low IGSF4 expression. The solid line represents patients with high IGSF4 expression, the dotted line represents patients with low IGSF4 expression. NR indicates nonremitter.
