NR5A2 and metastatic malignant neoplasm in the lymph nodes: As shown in Table 6, two variables (lymph node metastasis and NR5A2 rs3790844) were included in the regression model by stepwise selection of the covariant variables and rs3790844 SNP was shown to be an independent protective factor for GC with a 21.6% decreased risk (HR = 0.784, 95% CI = 0.646–0.951, p = 0.014).
