Low nuclear DARPP‐32 expression remained significantly associated with survival in multivariate Cox regression (P = .045, hazard ratio (HR) = 0.734, 95% confidence interval (CI) = 0.542‐0.993), when Figo stage, residual disease, tumour grade, tumour histology and median patient age were included (all with individual Kaplan‐Meier statistics of P = .001 or below). Here, PPP1R1B is linked to neoplasm.
