Survival of patients in the germinal center B-cell-like (GC), activated B-cell-like (ABC), and type III subgroups separated by redox signature score. Comparison of survival of patients separated into 4 quartiles by redox signature score within each subgroup. Patients in quartile 1 have the highest redox signature score. Quartiles are graphed as follows: quartile 1, thin solid line; quartile 2, dotted line; quartile 3, thick solid line; quartile 4, dashed line.
