Table 6 The discriminative ability of PCPT, ERSPC and IPRCv using the areas under the curve (AUC) and 95% confidence interval of the calculated probabilities for those whom the prostate volume is available. The p-values indicate if the difference between each risk calculator and IPRCv is significant
