2. Figure 1
Immunohistochemical staining patterns of β-catenin in ESCC (original magnification ×400). A, Preserved β-catenin staining at the cell membrane and normal staining in the cytoplasm. B, Reduced staining at the cell membrane and increased β-catenin staining in the cytoplasm. C, Reduced β-catenin staining at the cell membrane and no staining in the cytoplasm. D, Preserved β-catenin staining at the cell membrane and increased staining in the cytoplasm.

3. Figure 2
The Kaplan–Meier survival curve for protein expression of membranous β-catenin, indicating that patients with reduced membranous β-catenin protein expression had a poor prognosis (log–rank test, P = .005).

4. Figure 3
The Kaplan–Meier survival curve for protein expression of p53 and membranous β-catenin, showing that combined increased p53 expression and reduced β-catenin expression was associated with a poor prognosis (log–rank test, P = .012).
