Each solid circle represents an individual study in the meta-analysis. The curve is the regression line that summarizes the overall diagnostic accuracy. SE (AUC), standard error of AUC; Q*, an index defined by the point on the SROC curve where the sensitivity and specificity are equal; SE (Q*), standard error of Q* index.
