(A) Forest plot of prognostic lncRNAs: the red dots represented prognostic lncRNAs with hazard ratios > 1 (P<0.05) and the green dots represented prognostic lncRNAs with hazard ratios < 1 (P<0.05). (B) The LASSO Cox analysis of the 85 prognostic lncRNAs. (C) Tuning parameter (lambda) selection in the LASSO model were determined by 10-fold cross-validation; lncRNA, long non-coding RNA.
