Univariate Cox regression analysis shows that the factors affecting the poor prognosis of gastric cancer are age (p = 0.008114), stage (p = 0.000209), T classification (p = 0.031105), M classification (p = 0.026161), N classification (p = 0.004116), and LOX(p = 0.043712; Table 3). This evidence concerns the gene LOX and gastric cancer.
