The pooled sensitivity, specificity, positive and negative likelihood ratios (positive likelihood ratio [PLR] and negative likelihood ratio [NLR]), diagnostic odds ratio (DOR), and the area under the curve of summary receiver operating characteristic (SROC-AUC) were calculated using bivariate random-effects models.

The pooled PLR was 2.8 (95% CI, 2.5\u20133.1), the pooled NLR was 0.29 (95% CI, 0.25\u20130.35), and the pooled DOR was 9 (95% CI, 7\u201312). The SROC-AUC was 0.82 (95% CI, 0.78\u20130.85).
