Identification and assessment of the CRG subtypes. (A) The consensus matrix, consensus cumulative distribution function (CDF), and delta area by cluster analysis based on CRGs. Two clusters (k=2) would be best. (B) Principal component analysis of two CRG clusters. (C) Kaplan-Meier survival curves of two CRG clusters (p < 0.001). (D) Heatmap of clinical features and CRGs expressions between subtypes. LDH, lactate dehydrogenases; ES, extranodal sites; ECOG, The Eastern Cooperative Oncology Group performance score; COO, cell of origin; IPI, International Prognostic Index.
