Figure 4. Validation of the 6-DEirlncRNA pair signature. (A) Calculation of the AUC for risk score, age, sex, and TNM stage shows that risk score is the maximum. (B, C) The risk curve (B) and scatter plot (C) indicates that patients with high risk score had worse survival. (D–G) Scatter diagrams and strip chart (G) show that N stage (D), clinical stage (E), and T stage (F) were significantly related to the risk score.
