Figure 2: Receivers operating characteristic curves of percent free prostatic-specific antigen (%fPSA) and PSA in predicting high-grade prostate cancer for patients with PSA 4.0-10.0 ng ml−1 and PSA 10.1-20.0 ng ml−1. ( a ) Patients with PSA of 4.0-10.0 ng ml−1; ( b ) PSA 10.1-20.0 ng ml−1; ( c ) ≥60 years with PSA 4.0-10.0 ng ml−1; ( d ) ≥60 years with PSA 10.1-20.0 ng ml−1. Solid red line: %fPSA ; dashed blue line: PSA.
