Fig. 1 Correlation between uncorrected PSA-α1-protease inhibitor (API) and nonspecific background in 42 female sera without PSA immunoreactivity. PSA-α1-protease inhibitor and nonspecific background were determined in separate wells (y = −0.0003 + 0.9485 x, r = 0.91).

Fig. 2 Proportion of PSA-α1-protease inhibitor (API) plotted against proportion of free PSA in sera with total PSA 4 to 10 μg./l. from 44 prostate cancer cases and 210 controls. There was no correlation between proportions of PSA-α1-protease inhibitor and free PSA (r = 0.03, p = 0.56).

Fig. 3 ROC curves of total PSA, proportions of free PSA and PSA-α1-protease inhibitor (API), and probability of prostate cancer obtained by logistic regression analysis of logarithm of PSA-α1-protease inhibitor and proportion of free PSA in serum with PSA 4 to 10 μg./l. AUC, area under ROC curve. The Journal of Urology 2000 164, 1956-1960DOI: (10.1016/S0022-5347(05)66927-3) Copyright © 2000 American Urological Association, Inc. Terms and Conditions
