Representative expression of Nrf2 in the primary tumor using Western blotting and its association with pathologic characteristics. a. M; marker. N; non-tumor tissue. T; primary tumor tissue. LN; lymph node tissue. LN1 and LN2 were metastatic lymph node. The expressions of Nrf2 in the primary tumors were associated with tumor grade (b), pT stage (c), regional lymph node metastasis (d), and lymphovascular invasion (LVI) (e). The median value is the central line, the box is the interquartile range, the bars are the full range, and the points are the outliers
