Figure 2: Decision curve analysis of each factor in all patients for (a) PCa and (b) CSPCa, and in patients with PSA in gray zone for (c) PCa and (d) CSPCa. DCA curves show net benefit of age (blue line), tPSA (green line), prostate volume (yellow line), PSAD (purple line), PI-RADS v2 score (red line), and model 1 and model 2 (black line). Model 1 is constructed by a statistical association including tPSA and PI-RADS v2 score, whereas model 2 includes PSAD and PI-RADS v2 score. CSPCa: clinically significant prostate cancer; DCA: decision curve analysis; PCa: prostate cancer; PI-RADS v2: Prostate Imaging Reporting and Data System version 2; PSAD: prostate-specific antigen density; PV: prostate volume; tPSA: total prostate-specific antigen.
