EZR and neoplasm: High VIL2 expression remained associated with adverse survival in the breast cancer subgroup using multivariate Cox‐regression analysis (p < 0.001, HR = 1.400, 95% CI = 1.161–1.689) when the potential confounding factors of tumour size, tumour grade, ER status, PgR status and HER2 status were included (all with individual Kaplan–Meier log‐rank statistics of p < 0.001) (Table 2C).
