We included cross-sectional studies that evaluated the diagnostic accuracy of UBT in adult patients with dyspeptic symptoms. Diagnostic accuracy measures were pooled using the random-effects model. Out of studies identified, only 23 met the eligibility criteria.

There was significant variation in the type of reference standard tests used across studies. Pooled sensitivity was 0. prueba de urease en aliento

Likelihood ratio for a positive test was 12 and for a negative test was 0. Meta-analyses were associated with a significant statistical heterogeneity that remained unexplained after subgroup analysis. The included studies had a moderate risk of bias. UBT has high diagnostic accuracy for detecting H.

We conducted systemic review and meta-analysis to explore the available evidence and provide pooled diagnostic accuracy measures.

Our meta-analysis showed that UBT has high diagnostic accuracy for detecting H.
