Race-stratified calibration curves and the risk probability distribution histograms for clinically significant prostate cancer for PBCG and PCPT risk calculators. PCPT = Prostate Cancer Prevention Trial risk calculator; PBCG = Prostate Biopsy Collaborative Group risk calculator; Blue lines and histograms = PCPT; Yellow lines and histograms = PBCG; Black lines = 45-degree line representing perfect calibration
