Diagnostic accuracy measures such as sensitivity, specificity, likelihood ratios (LRs), diagnostic odds ratio (DOR), and area under the curve (AUC) were pooled using a bivariate random-effects model. We also assessed heterogeneity, threshold effect, and publication bias. The review protocol was prospectively registered in the PROSPERO under registration number CRD42024621782.</p><p><strong>Results: </strong>Five studies with 293 patients were included. The pooled sensitivity and specificity were 91.4% (95% CI: 83.5-95.7; I² = 25.4%) and 91.1% (95% CI: 63.8-98.3; I² = 82.0%), respectively. The AUC was 0.919 (95% CI: 0.80-0.94), and the DOR was 54.1 (95% CI: 13.6-215.5; I² = 57%). The positive LR (LR+) and negative LR (LR-) were 10.3 (95% CI: 2.15-49.6) and 0.10 (95% CI: 0.06-0.2), respectively, indicating strong diagnostic performance. Sensitivity heterogeneity was resolved (I² = 0%) after excluding one outlier study, yielding a revised pooled sensitivity of 88.6% (95% CI: 81.0%-93.1%).
