Evaluation and validation predictive performance of GInLncSig on OS in PAAD patients. Kaplan–Meier survival curves for high-risk and low-risk subsets were plotted according to GInLncSig scores in the training set A, test set C, and TCGA set E. Patients in the low-risk group showed longer survival compared with patients in the high-risk group (log-rank test, P < 0.05). The ROC curve of 1-year survival prediction of GInLncSig in training set B, test set D and TCGA set F
