Figure 4

ROC analysis for FljB iELISA, TAT and western blotting. Overlay of all results of the ROC (receiver operating characteristics) analysis for all samples (overall) and for TAT (a), western blotting (b) and FljB iELISA (c), separately, with the corresponding area under the ROC curve (AUC). The true infection positives (n = 88) and true negatives (n = 88) were used as reference populations. The ROC plots the true positive rate (sensitivity) against the false positives (100-specificity).
