CIR for different NPM1^mut/ABL1 cutoffs after allogeneic SCT beginning from the first MRD assessment post-SCT. CIR analyzed by Gray’s regression model indicates that the probability of relapse correlates with MRD burden. CIR was investigated for the following NPM1^mut/ABL1 cutoffs: (A) 0.01%, (B) 1%, (C) 2%, and (D) 10%.
