Establishment of a risk stratification model based on genes differentially expressed between the subtypes. A-C Patients with low risk scores exhibited longer survival times than those with high scores in the three cohorts (TCGA, ICGC, and GSE57495). D-F Risk plots depicting the risk scores and survival times of each patients. A heatmap depicting the expression of core genes in pancreatic cancer patients is also shown (TCGA, ICGC, and GSE57495). G-I The high AUC in the training set (TCGA) and validation set (ICGC and GSE57495) indicates the good predictive performance of our risk model
