Construction and verification of 6-lncRNA survival prediction model. (A) Lasso cox regression analysis to screen OS-related DELs; (B) Multivariate Cox regression analysis to build a forest diagram of the risk model; (C) Kaplan–Meier to draw the survival curve of each lncRNA in the risk model; (D, E) the correlation between the risk model and OS in the training group (D) and the validation group (E). Risk curve (top), Survival status graph (middle), and Risk heatmap (bottom).
