High levels of UCHL1 mark patients with non-mBL at high risk for relapse. Overall survival is plotted using the Kaplan-Meier method for 92 patients with non-mBL stratified based on the level of UCHL1 mRNA as shown. Those with ABC gene expression profile and double hit (DH) lymphoma (as defined by reported fluorescence in situ hybridization studies for MYC, BCL2, and BCL6) were excluded as shown. Data were extracted from GSE4475¹⁴  and analyzed using the R2: Genomics Analysis and Visualization Platform (http://r2.amc.nl). P value was determined using the Mantel-Cox log-rank test.
