Kaplan-Meier survival curves for OS of patients with CEBPAmu in bZIP comparing the 3 genotypes (GATA2 positive/WT1 negative, GATA2 negative/WT1 positive, GATA2 negative/WT1 negative). Kaplan-Meier curves were stratified according to the 3 genotypes: red, GATA2 positive/WT1 negative; blue, GATA2 negative/WT1 positive; and gray, GATA2 negative/WT1 negative. There was no genotype of GATA2 positive/WT1 positive. (A) Kaplan-Meier curve of OS for all patients (among the 3 groups P = .410; GATA2 positive/WT1 negative vs GATA2 negative/WT1 positive, P = .154; GATA2 negative/WT1 positive vs GATA2 negative/WT1 negative, P = .483; GATA2 positive/WT1 negative vs GATA2 negative/WT1 negative, P = .366). (B) Kaplan-Meier curve of OS for patients aged ≤70 years and with intermediate-risk karyotype (among the 3 groups, P = .072; GATA2 positive/WT1 negative vs GATA2 negative/WT1 positive, P = .016; GATA2 negative/WT1 positive vs GATA2 negative/WT1 negative, P = .208; GATA2 positive/WT1 negative vs GATA2 negative/WT1 negative, P = .113).
