A Novel Cuproptosis-Associated Gene Signature to Predict Prognosis in Patients with Pancreatic Cancer

Figure 5

Validating the prognostic predictive power of the Cox risk models. ROC curve of the Cox risk model and clinical characteristics in the training group (a), validation group (b), and entire cohort (c). ROC curves of risk models predict 1-, 3-, and 5-year OS rates in the training group (d), validation group (e), and entire cohort (f). PCA of DEGs (g), cuproptosis genes (h), cuproptosis-related genes (i), and 8-gene signature (j) in PAAD patients. ROC: receiver operating characteristic; AUC: area under ROC curve; OS: overall survival; DEG: differentially expressed gene; PCA: principal component analysis; PAAD: pancreatic cancer.
