Development and validation of an epithelial–mesenchymal transition-related gene signature for predicting prognosis

Figure 3 Identification of the potential epithelial-mesenchymal transition-associated genes in the derivation cohort. A: Venn diagram to classify differentially expressed genes between tumor and adjacent normal tissue that were related to overall survival (OS); B: Thirty-one of the 33 overlapping genes were upregulated in cancer tissue; C: Forest plots presenting the outcomes of univariate Cox regression analysis between gene expression and OS; D: Protein-protein interaction network downloaded from the STRING database showing the interactions among the potential genes; E: The correlation network of the potential genes: correlation coefficients are shown with different colors; the number of lines indicates the correlation strength.
