What was measured

Bone marrow MRD status is defined as negative with \< .01 detectable leukemia cells.

Analysis population: Patients on Arm/Group "Prednisone and High Dose Methotrexate (non randomly assigned)" are not included in the OM as there were no survivors for the 5 year duration. Cohort of MRD Negative patients some of whom have had EFS/OS events after 5 years or have minimum 5 years of follow-up.
