VEGFB and gastric cancer: Pearson's correlation analysis revealed that the protein expression-modified GPSGC risk score was strongly positively correlated with TGFβ1 protein expression (r = 0.5763; P < 0.0001; Figure 6E) and VEGFB protein expression (r = 0.5855; P < 0.0001; Figure 6F) in the tissues of 186 GC patients.
