Figure 4. The ROC curves by establishing the risk coefficient model through the immune lncRNA pairs of ccRCC. (A) The 1, 3, and 5-year ROC curves were obtained using model construction. The AUC values were all higher than 0.83. (B) One-year ROC curve with maximum AUC value obtained by the model. (C) The cut-off value of 2.822 that distinguishes between high- and low-risk patients was obtained using the best fit.
