Figure 1

Receiver operator characteristics curves showing the accuracies of top individual analytes in discriminating between active TB and latent TB infection. Receiver operator characteristic (ROC) curves for the accuracies of single analytes to differentiate between active TB and LTBI in QFT positive individuals. Only ROC curves for markers that differentiated between the two infection states with AUCs ≥ 0.73 are shown. AUC = Area under the curve.
