KLK3 and cancer: We showed that MRITBx with the predictor PSA is a better discriminator of high cancers and not high cancers with the area under the ROC curve 92.6%, the sensitivity, 93.3% and the specificity, 42.6%, than the one just based on MRITBx alone (Cohen’s Kappa = 0.16, sensitivity = 77.8% and specificity = 85.3%).
