Figure 4. Receiver operating characteristics (ROC) curve for the CFA, EXO and TCA antigens derived from Paracoccidioides lutzii EPM208 isolate.

Figure 4

The ROC is plotted between the true-positive rate (sensitivity) on the y-axis, and the false-positive rate (100-specificity) on the x-axis. The area under the curve (AUC) represents the accuracy of the ID test which was 1.0, IC 0.95–1.0, p<0.0001 for the CFA, 0.74±0.06, IC 0.68–0.87, p<0.0001 for the EXO and 0.58±0.04, IC 0.47–0.69, p = 0.0641 for the TCA antigens. The higher AUC above 0.5, the better the test.
