Fig. 4From: Heterogeneity of prostate-specific membrane antigen (PSMA) and PSMA-ligand uptake detection combining autoradiography and postoperative pathology in primary prostate cancerA Box plot of the correlation between Gleason Score and IRS. An higher IRS score was observed in Gleason Score ≥ 8 (***Mann–Whitney U test, p < 0.001). B Box plot indicating a higher IRS score in ROIs with a positive signal in ARG (***Mann–Whitney U test, p < 0.001). ARG = autoradiography, IRS = immunoreactive score, ROI = region of interestBack to article page
