MRD indicates minimal residual disease; HR, hematologic relapse; CR, complete remission; CCR, continuous CR; MR, molecular relapse; mCR, molecular CR; and CNS, central nervous system.
Numbers do not add, as some patients were successfully treated in first MR.
In the 12 months prior to HR, there were no CR samples.
