Association of NF-κB expression with Notch1 expression in ESCC. (A) NF-κB expression was negatively correlated with Notch1 expression in ESCC tissue. (B) The mean histoscore of NF-κB expression was lower in ESCC tissue with high levels of Notch1 expression (3.52 ± 0.53) than in those with low levels of Notch1 expression (6.71 ± 0.74; P < 0.05).
