Fig. 5From: Molecular signatures of tumor progression in pancreatic adenocarcinoma identified by energy metabolism characteristicsExternal validation of the robustness of the 4-gene signature in the GSE57495 and ICGC PAAD cohorts. A Risk score, survival time, survival status, and expression of the 4-gene signature in the GSE57495 dataset; B ROC curve of the 4-gene signature for 1-year, 3-year, and 5-year survival in the GSE57495 cohort; C Kaplan–Meier survival curve based on the 4-gene signature in the GSE57495 cohorts. D Risk score, survival time, survival status, and expression of the 4-gene signature in the ICGC PAAD dataset; E ROC curve of the 4-gene signature for 1-year, 3-year, and 5-year survival in the ICGC PAAD cohort; (D) Kaplan–Meier survival curve based on the 4-gene signature in the ICGC PAAD cohorts. ROC, receiver operating characteristic; AUC, area under the curve; HR, hazard ratio; CI, confidence intervalBack to article page
