Establishment of a pair-risk assessment model by differentially expressed lncRNA pairs. A Plot shows the maximum AUC value of the model based on the core irlncRNA pairs. B The 1-, 5-, and 10-year ROC curves of the model suggest that all AUC values are over 0.70. C The maximum inflection point is recognized by the AIC. D Comparing risk score ROC curves with other common clinical characteristics indicate the superiority of this pair-risk model
