What was measured

PIF is defined as participants who received treatment for ALL but never achieved CR or CRi by the end of induction. PIF is not limited by the number of unsuccessful treatments; this disease status only applies to recipients who have never been in CR or CRi. CR is defined as meeting all the following for at least 4 weeks (that is no recurrence): 1. No circulating blasts and \<5% blasts in the BM. 2. Normal maturation of all cellular components in the BM. 3. No extramedullary disease (CNS involvement, lymphadenopathy, splenomegaly, skin/gum infiltration, testicular mass). 4. ANC \>1000/mcL (or \>1.0\*10\^9/L). 5. Platelets \>100,000/mcL (or \>100\*10\^9/L). CRi is defined as hematologic complete remission with incomplete hematologic recovery and meeting all criteria for CR except platelet count and/or ANC.
