Establishment of BRRGs prognostic signature. (A,B) LASSO regression analysis for most suitable λ. (C) The distribution of resistance scores and survival status of DLBCL in training cohort, the dots represent the resistance score, survival time, and outcome for each patient. (D) Kaplan–Meier survival curve of high- and low-resistance score groups in training cohort. (E) PCA plot in the training cohort. The red dots represent high-resistance score group patients and blue dots represent low-resistance score group patients. (F) ROC curve of 2-, 3-, and 5-year survival prediction in the training cohort.
