We revealed that the significant variables for LNM were GAP43 expression (odds ratio [OR] = 2.462, 95% confidence interval [CI] = 1.678‐3.594, P < 0.001), age (OR = 0.62, 95% CI = 0.427‐0.889, P = 0.012), histological type (OR = 0.646, 95% CI = 1.544‐3.680, P < 0.001), tumour size (OR = 2.496, 95% CI = 1.619‐3.764, P < 0.001), gender (OR = 1.551, 95% CI = 1.022‐2.353, P = 0.039) and disease stage (OR = 3.493, 95% CI = 2.316‐5.268, P < 0.001; Table 4) in univariate logistic regression analysis. The gene discussed is GAP43; the disease is neoplasm.
