Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	5-year event free survival rate		Up to 5-years
Secondary	Confirmation of the therapeutic effect of the initial treatment response	Relapse-free survival between two groups(NGS-MRD positive vs. NGS MRD negative after induction) offsets by NGS MRD based stratified treatment	Up to 5-years
Secondary	Disease prognosis-related factor	Relapse-free survival according to presence or absence of known good prognosis factors(high hyperdilpoidy, ETV6/RUNX1, Trisomy 4/10/17) have no clinical significance when NGS MRD based stratified treatment is performed.	Up to 5-years
