From: The meta-analysis for ideal cytokines to distinguish the latent and active TB infection
Summary Receiver Operating Characteristic curves of each cytokine for discriminating between active TB and LTBI. a IL-2, b IP-10, c IL-5, d IL-13, e IFN-γ, f IL-10, g TNF-α. Each solid circle represents each study in the meta-analysis. The curve is the regression line that summarizes the overall diagnostic accuracy. SROC = summary receiver operating characteristic; AUC = area under the curve; SE (AUC) = standard error of AUC; Q* = an index defined by the point on the SROC curve where the sensitivity and specificity are equal, which is the point closest to the top-left corner of the ROC space; SE (Q*) = standard error of Q* index
