Discovery of Prognostic Signature Genes for Overall Survival Prediction in Gastric Cancer

Figure 2

The gene expression levels of the seven gene signatures in the two risk groups. The differential expression levels of the seven prognostic genes between the high-risk and low-risk groups in TCGA (a) and GSE84433 (b) datasets, which were referred to as training and validation datasets, respectively. The red and blue boxes represent the high-risk and low-risk groups. (, , , and ).
