Table 2 Comparison of A+PSA index and PSA based on mean values at 3 different dilutions

From: A novel multiplex assay combining autoantibodies plus PSA has potential implications for classification of prostate cancer from non-malignant cases

Variables Sensitivity Specificity False positive Accuracy AUC
PSA alone in all patients 52% (68/131) 79% (95/121) 21% (26/121) 65% 0.66
A+PSA in all patients 79% (103/131) 84% (102/121) 16% (19/121) 81% 0.91 P < 0.0001
