Immunophenotypic characteristics and translocation status of PMBLsig⁺ tumors and other tumors with DLBCL morphology. Forest plots at the left show enrichment or depletion of positive tumors among the PMBLsig⁺ group compared with other DLBCLs for each marker/translocation. Bar plots at the right represent the fraction of cases positive for each marker/translocation. ABC, activated B-cell–like; EBV, Epstein-Barr virus; HGBL-DH/TH, high-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangement; MHC, major histocompatibility complex; UNC, unclassified.
