Fig. 3From: Developing a nomogram based on multiparametric magnetic resonance imaging for forecasting high-grade prostate cancer to reduce unnecessary biopsies within the prostate-specific antigen gray zoneNomogram shows logistic model for prediction of high-grade prostate cancer. Predictive nomogram for high-grade cancer incorporating age, PI-RADS v2 score, adjusted PSAD. Draw a line upward to number of points in each category. Sum the points and draw a line downward to find the risk of a positive biopsyBack to article page
