ABC, activated B cell; GCB, germinal centre B cells; IPI, International Prognostic Index.

*As estimated from the Kaplan–Meier curves.

†As determined by χ² test, unless stated otherwise.

‡Data concerning stage and therefore IPI could not be retrieved in one patient.

§Data concerning the ABC/GCB profile could not be retrieved in two patients.
