GRFS probability in all ALL patients. GRFS probability in all ALL patients (A-B), ALL patients ≥4 years of age (C-D), and AML patients (E-F) receiving CloFluBu conditioning. Two-year GRFS with standard errors is provided, with P values calculated with the Cox proportional hazard model and correction for covariates where appropriate (Table 2; supplemental Table 1).
