FOLH1 and neoplasm: Despite half of the pT4b tumours expressed 0–10% PSMA, this distribution did not reach statistical significance due to multiple testing (p = .04), see Table 1. A multivariate Cox-proportional Hazard model with Firth’s correction showed a significant relation between low PSMA expression (0–10%) and worse 10-years RFS (HR 3.0, 95% CI 1.1–8.5, p = .04).
