Fig. 1: Kaplan–Meier survival analysis for event-free survival (panels a, c, and e) and overall survival (panels b, d, and f) in relation to molecular characteristics of diffuse large B-cell lymphomas treated in the PETAL trial.

a, b Cell of origin as determined by gene expression profiling (a, p = 0.2077; b, p = 0.2020). ABC, activated B-cell-like; GCB, germinal center B-cell lymphomas. c, d MYC-breaks (c, p = 0.1206; d, p = 0.0083). e, f “Double-hit” status (e, p = 0.0400; f, p = 0.0049). PET, positron emission tomography
