Plots for event-free survival of T-LBL/ALL patients according to the age (a, b), bone marrow involvement (c), or PLZF expression (d). Event-free survival time was calculated from the date of diagnosis to the date of disease progression/relapse, death, or the date of the last follow-up. Survival analysis was performed using the Kaplan and Meier method with the log-rank test.
