3.3 | Pooled results
The pooled sensitivity and specificity of RAC for the endoscopic
diagnosis of H. pylori infection were 0.98 (95% CI 0.95 to 0.99) and
0.75 (95% CI 0.54 to 0.88), respectively (Figure 2 ). The
pooled PLR and NLR were 3.8 (95% CI 1.9 to 7.7) and 0.03 (95% CI 0.02
to 0.07), respectively (Supplementary Figure 2 ). The DOR was
115 (95% CI 36 to 365) (Supplementary Figure 3 ). The area
under the summary receiver operating characteristic curve was 0.98 (95%
CI 0.96 to 0.99), suggesting a high overall diagnostic accuracy for H.
pylori infection (Figure 3 ).
