2. Figure 1 Outline of treatment regimens for clinical risk groups
IM=interim maintenance. DI=delayed intensification. BFM=Berlin-Frankfurt-Munster. MRD=minimal residual disease. MRD high-risk patients assigned to augmented therapy transferred to regimen C after induction.

Trial profile
MRD=minimal residual disease. SER=slow early response. *One patient had Burkitt's lymphoma, one T-cell lymphoma, one T-cell non-Hodgkin lymphoma, one mature B-cell acute lymphoblastic leukaemia, two acute myeloid leukaemia, five mixed-phenotype acute leukaemia, and one precursor B non-Hodgkin lymphoma. †52 patients were transferred to EsPhALL and seven to another Philadelphia chromosome-positive study protocol. ‡No high-risk randomised patients were lost to follow-up within 1 year or excluded from analysis.

Event-free survival (A) and relapse risk (B) by randomly allocated treatment group
44 event-free survival events occurred in the standard group vs 28 in the augmented group. 35 patients in the standard group had a relapse vs 20 in the augmented group. Numbers at risk apply to both graphs.

5. Figure 4 Subgroup analyses for event-free survival
O–E=observed events minus expected events. OR=odds ratio. NCI=National Cancer Institute. MRD=minimal residual disease. BCP-ALL=B-cell precursor acute lymphoblastic leukaemia. *95% CI for overall results. †Smaller numbers of patients were included in the overall adjusted analysis because the MRD level on day 29 was unknown in six patients and the cytogenetic risk group was unknown in 32 patients. Cytogenetic risk group was analysed as two groups: BCP-ALL good and BCP-ALL intermediate/poor. χ21=1 degree of freedom in χ2 test.
