A Clinical nomogram predicting csPCa. The clinical nomogram predicting the probability of csPCa in patients undergoing prostate biopsy based on PSAd and DRE results. Instructions: locate the patient’s prebiopsy PSAd on the PSAd axis. Draw a line straight upward to the point axis to determine how many points toward the probability of csPCa the patient receives for his PSAd level. Repeat the process for each additional variable. Sum the points for each predictor. Locate the final sum on the total-point axis. Draw a line straight down to find the patient’s probability of having csPCa. B bpMRI PI-RADS v2.1-based nomogram predicting csPCa. The nomogram predicting the probability of csPCa in patients undergoing prostate biopsy based on the PSAd, DRE outcomes and the bpMRI PI-RADS v2.1 score. csPCa = Clinically significant prostate cancer; PSAd = prostate-specific antigen density; DRE = Digital rectal examination; PI-RADS v2.1, Prostate Imaging Reporting and Data System version 2.1; bpMRI = biparametric Magnetic Resonance Imaging
