Expression and prognostic value of FoxP3 in PESCC. (a) Representative multi-IF images of two samples showing FoxP3/CD4 ratios in the stroma. Scale bar, 100 μm. (b) Representative multi-IF images showing two samples with high (left) and low (right) FoxP3/CD8 ratios in stroma. Scale bar, 100 μm. (c) Rich FoxP3 (red line, ) was associated with significantly shorter OS than poor FoxP3 (blue line, ). (d) A high FoxP3/CD8 ratio (red line, ) was associated with shorter OS than a low FoxP3/CD8 ratio (blue line, ).
