Figure 3. Establishment of a risk assessment model based on DEmlncRNA. The curve of each AUC value generated by ROCs of DEmlncRNAs was drawn, and the highest point of AUC was determined; The maximum inflection point is the cut-off point acquired from AIC (A and B). The 1-year, 2-year, and 3-year ROC of the optimal model showed that all AUC values exceeded 0.65 (C). Compared with other common clinical features, the 1-year ROC curves showed the superiority of the risk score against age and gender (D).
