Outcomes in MRD^– patients. (A) Multivariable competing risk regression of factors associated with relapse (left) and Cox regression for OS (right) in MRD^– patients. The HR for age is per 10 years, and WCC and platelets were log-transformed. (B) Kaplan-Meier curves of OS by FLT3-ITD for all patients (left), MRD^– patients (middle), and MRD-positive patients (right). ∗Cytogenetic risk is with normal karyotype as the reference group. ^NPM1 mutation type is with type A as the reference group.
