Identification of Six Potentially Long Noncoding RNAs as Biomarkers Involved Competitive Endogenous RNA in Clear Cell Renal Cell Carcinoma

Kaplan-Meier (KM) method and receiver operating characteristic (ROC) analysis of the sensitivity and specificity for overall survival predicted by the six lncRNA risk score. (a) KM plot for a discriminative median patient risk scores with six lncRNA expressions about overall survival. P value was calculated by the log-rank test in R software. (b) An ROC curve was built on a univariate regression model based on patient risk scores. The score performance of ROC was estimated by calculating the area under the ROC.
