Figure 4. Development and verification of OS-nomogram and recurrence-nomogram. (A) OS-nomogram based on 8-lncRNAs-based classifier, TNM M classifier and Performance Status; (B) recurrence-nomogram based on 14-lncRNAs-based classifier, TNM M classifier and Performance Status; (C–E) The 1, 3, and 5-year Time-dependent ROC curves compare the prognostic accuracy of the OS-nomogram; (F) 1, 3, and 5 year calibration curve and C-index of the OS-nomogram; (G–I) The 1, 3, and 5-year Time-dependent ROC curves compare the prognostic accuracy of the recurrence-nomogram; (J) 1, 3, and 5 year calibration curve and C-index of the recurrence-nomogram. OS, overall survival; lncRNA, long non-coding RNA; ROC, receiver operating characteristic; C-index, concordance index.
