We then performed a logistic regression to identify biomarkers with independent value to predict unsustained CR. Elevated LDH levels (HR: 2.9 [1.1 - 8.0], P =.038) and >20% PCs (HR: 2.8 [1.2 - 6.7], P =.020) at diagnosis together with persistent MRD (HR: 4.3 [1.9 - 9.6], P <.001) had independent value to predict unsustained CR in a multivariable analysis.
