IPRCv nomograms. The nomograms (based on IPRCv which including prostate volume) for PCa model is on the left and high-grade PCa model on the right. The horizontal line on the top labelled `points’ allows the effect size of each variable to be assessed. To use the nomogram draw a straight line from the values/levels of each variable to measure its corresponding point. The total points on the bottom are then mapped to obtain the risk of cancer or high-grade cancer
