Appendix CAlternative Parameterizations of the Hierarchical Summary Receiver Operating Characteristic Curve

We followed Arends 2008 [25] in constructing alternative hierarchical summary receiver operating (HSROC) curves based on the bivariate random effects meta-analysis model. Here, η̄ is the summary logit-transformed true positive rate, ξ̄ is the summary logit-transformed false positive rate (1 – specificity), ηi and ξi are respectively the logit-transformed true positive rate and the false positive rate in the i-th study; ση2 and σξ2 are the variances of the logit-transformed true and false positive rates, respectively; σξη is their covariance.

After fitting the bivariate model, we obtained the HSROC lines, as shown in Table C-1.
