The eight-lncRNA signature-focused risk score in prognosis of overall survival in the GSE37745 patient set. a Receiver operating characteristic (ROC) analysis of the risk scores for overall survival prediction in the training dataset. The area under the curve (AUC) was calculated for ROC curves, and sensitivity and specificity were calculated to assess score performance. b The Kaplan–Meier curve for overall survival of two patient groups with high- and low-risk scores in the GSE37745 training set (n = 196). The differences between the two curves were evaluated by the two-sided log-rank test. c The eight lncRNA-based risk score distribution, patients’ survival status and heatmap of the eight lncRNA expression profiles. The black dotted line represents the cutoff value of the risk score derived from the training set which separated patients into high- and low-risk groups.
