The Prostate Risk Indicator () was developed in Rotterdam and consists of 4 risk calculators, of which the first 3 predict the probability of detecting a prostate cancer (van den Bergh et al. 2008). This nomogram is based on 6288 Dutch men enrolled in the European Randomised Study of Screening for Prostate Cancer (ERSPC) (Schroder et al. 2009). The risk calculator comprises 4 risk indicators, the first 3 of which predict the possibility of a positive prostate biopsy. The first 2 prostate risk indicators produced by this group may be used by the general public whereas the other risk calculators are intended to be used by urologists.
