**Figure 3.** **Development and verification of 8-lncRNAs-based and 14-lncRNAs-based classifiers.** (**A**) LASSO coefficient profiles of the 86 Significant difference lncRNAs in OS set. A vertical line is drawn at the value chosen by 10-fold cross-validation; (**B**) Ten-time cross-validation for tuning parameter selection in the LASSO model; (**C**, **D**) Time-dependent ROC curves and calibration curves of 8-lncRNAs-based classifier; (**E**) Time-dependent ROC curves of Liao’s biomarker for overall survival; (**F**) LASSO coefficient profiles of the 21 Significant difference lncRNAs in recurrence set, A vertical line is drawn at the value chosen by 10-fold cross-validation; (**G**) Ten-time cross-validation for tuning parameter selection in the LASSO model; (**H**) Time-dependent ROC curves and calibration curves of 14-lncRNAs-based classifier. LASSO, least absolute shrinkage and selection operator method; lncRNA, long non-coding RNA; OS, overall survival; ROC, receiver operating characteristic.
