Fig. 5From: The identification of liver metastasis- and prognosis-associated genes in pancreatic ductal adenocarcinomaHub gene expression associations with PDAC prognosis based on the TCGA PAAD datasets (n = 177). OS curves of 16 hub genes in TCGA PAAD patients obtained using the Kaplan–Meier method. The patients classified into high- (n = 88) or low-expression (n = 89) groups for these 16 genes, respectively, and the two groups compared with log-rank test. P < 0.05 was considered statistically significantBack to article page
