Comparison of long-term, progression-free, and overall survival. Kaplan-Meier curves comparing the long-term (A) progression-free survival (PFS) and overall survival (OS) of the entire cohort; PFS (B) and OS (C) by induction regimen; PFS (D) and OS (E) comparing R-CHOP with other intensified induction regimens (ie, DA-EPOCH, Hyper CVAD, and CODOX/M-IVAC).
