Individual sensitivity, specificity, and accuracy achieved when ten trials are scored (). and are, respectively, the number of correctly classified targets and nontargets. Meanwhile, the correctly labeled target and nontarget count is . AUROC: area under the receiver operating characteristic curve [37]. SD: standard deviation.
