Logistic regression analysis for LN metastasis. Multivariate analysis for nodal metastasis was performed using a logistic regression model. The presence of vessel invasion and high GFPT1 expression were found to be independently associated with nodal metastasis. OR, odds ratio; GFPT1, glutamine-fructose-6-phosphate transaminase 1; CA199, carbohydrate antigen 199
