Figure 2. ROC curves based on the serum expression of miR-145. A. miR-145 could be used to distinguish LTB patients from the healthy controls with an AUC of 0.815. B. miR-145 had high diagnostic value for the differentiation between ATB patients and healthy controls with an AUC of 0.934. C. miR-145 had the diagnostic potential to screen ATB cases from the LTB cases with an AUC value of 0.785. HC, healthy control; LTB, latent tuberculosis; ATB, active tuberculosis; AUC, area under the ROC curve.
