OSM and neoplasm: As shown in Figure 6C and Table 1, low expression of OSM correlates positively with lymphatic metastasis (chi-square test: p=0.003; Wilcox test: p<0.001), distant metastasis (chi-square test: p=0.045; Wilcox test: p=0.025), vascular invasion (chi-square test: p=0.001; Wilcox test: p<0.001), and tumor stage (chi-square test: p=0.033; Wilcox test: p=0.026).
