LncRNA risk score performance in the GSE39582 training dataset. The distribution of signature risk score, patients’ survival status and seven-lncRNA expression were analyzed in the GSE39582 training patients (N = 279). a The distribution of lncRNA signature risk score distribution; b The survival status and time of corresponding patient; c The heatmap of the lncRNA expression value. Rows represent lncRNAs and columns for patients. The black line means the median risk score cutoff dividing patients into low-risk and high-risk groups
