Identifying the LncRNA signature in the training dataset. (A), Univariate Cox proportional hazards regression analysis of the lncRNA expression profiling data in the training dataset. (B), Identifying the lncRNAs by RFSC algorithm. (C). The AUC of all 511 signatures were calculated and the nine highest AUC for k = 1, 2…9 is shown in the plot by ROC analysis for the lncRNA signatures predicting model in the training dataset. (D), Agarose electrophoresis of selected lncRNAs PCR products.
