Fig. 4From: Evaluation of Mycobacterium tuberculosis specific antigen-stimulated CD27−CD38+IFN-γ+CD4+ T cells for discrimination of active tuberculosisReceiver operating characteristics (ROC) curves and accuracy for the diagnosis of active tuberculosis (ATB). A ROC curves of different indicators for the diagnosis of ATB. B Sensitivity and specificity corresponding to the cutoff values. The dotted line indicates 80% sensitivity and 80% specificity. C The dotted line represents the cutoff value of CD4+IFN-γ+CD38+CD27−/CD4+ as 1.34 × 10–4.
