Nomogram prediction model for predicting prostate cancer, clinically significant prostate cancer and unfavourable prostate cancer at the time of biopsy. Steps for assessing cancer probability from the nomogram are as follows: 1. Locate the patient's variable Age on corresponding axis. 2. Draw a line straight download to the score axis to determine how many points towards the probability of cancer the patient is scored for his Age. 3. Repeat the process for each additional variable [ 4K score test, prior negative biopsy, DRE, MRI Prostate volume and MRI PI‐RADS score]. 4. Total the points for each of the predictors. 5. Locate the final sum on the total score axis. 6. Draw a line straight up to find the patient's probability of having PCa, csPCa and uPCa. Total scores correspond to a probability value for PCa, csPCa and uPCa. Abbreviations: PCa‐ prostate cancer, csPCa‐ clinically significant prostate cancer, uPCa‐unfavourable PCa DRE‐ digital rectal examination finding, PI‐RADS‐ Prostate Imaging Reporting and Data System
