Summary Receiver Operator Curve (SROC) plot for line probe assay. Each solid circle (culture isolate) and open rectangle (clinical specimen) 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.
