Figure 1

Receiver operating characteristic curves representing the diagnostic ability of blood serum biomarkers in predicting overall prostate cancer. Abbreviations: ISUP: International Society of Urological Pathology; fPSA: free prostate-specific antigen; %fPSA: free to total PSA ratio; phi: Prostate Health Index; PHID: phi density; PSAD: PSA density; ROC: receiver operating characteristic; tPSA: total PSA; %p2PSA: p2PSA to fPSA ratio. All significant differences are marked with asterisk () and (): for tPSA vs. p2PSA, phi, %fPSA, and PSAD. for PHID vs. tPSA, fPSA, %fPSA, p2PSA, %p2PSA, and phi.
