A three-lncRNA signature predicts LGG patient prognosis. (A) Construction of risk model by multivariate Cox regression; (B) Heatmap of seven lncRNA expression profiles and distribution of seven associated lncRNA-based risk scores; (C) Distributions showing patient status in high- and low-risk groups; (D) Mortality rates in high- and low-risk groups. (E) Survival curves of patients assigned to high- and low-risk groups; (F) ROC curves showing the predictive efficiency of the risk signature on survival.
