Four-gene prognostic model of pancreatic cancer in training and validation cohort. a Construction of prognostic risk model of pancreatic cancer in training cohort-GSE78229. Yellow and blue represent patients with low and high risk scores. We defined high risk group as risk score ≥ median, low risk group as risk score < median. b Validation of prognostic risk model of pancreatic cancer in GSE28735. c Validation of prognostic risk model of pancreatic cancer in TCGA.
