Forest plots of summary estimates of sensitivity and specificity stratified by RADT category. The black boxes indicate the sensitivity and specificity, and the horizontal black lines indicate the corresponding 95% CIs for each result in each RADT category. For each RADT category with more than 3 results, a diamond is centered on the summary estimate for sensitivity and specificity, with points on the corresponding 95% CI, as estimated jointly by bivariate random-effects regression. FN, false-negative; FP, false-positive; IC, immunochromatographic assay; TN, true-negative; TP, true-positive.
S-ROC curve and sensitivity and specificity stratified by RADT category. In each panel, all pairs of sensitivity and specificity from RADT categories with more than 3 results are represented as a cross (+). A black cross indicates the pair is from the indicated RADT category, whereas a gray cross shows pairs from all other RADT categories with more than 3 results. Each panel also shows for the indicated RADT category the summary estimate (black closed circle) and corresponding 95% confidence ellipse (thick black line), and the S-ROC curve (thin black line), which were derived from bivariate random-effects regression. In addition, each panel shows in gray the summary estimate and 95% confidence ellipse, and S-ROC curve, for all other RADT categories with more than 3 results. IC, immunochromatographic assay.
