EZR and breast cancer: High ezrin expression remained associated with adverse survival in the breast cancer subgroup using multivariate Cox‐regression analysis (p = 0.007, HR = 1.435, 95% CI = 1.103–1.868) when the potential confounding factors of tumour size, tumour stage, tumour grade and vascular invasion were included (all with individual Kaplan–Meier log‐rank statistics of p < 0.001) (Table 2B).
