To investigate whether expression levels of TPα and/or TPβ may add independent prognostic value over (i) Gleason scoring (GS) and (ii) pathological tumour staging (PTS) in the prediction of BCR-free survival time following surgery, additional multivariate time-to-event analyses were carried out (Supplementary Figure S4 and Supplementary Figure S5). This evidence concerns the gene PLAT and neoplasm.
