To our knowledge, this is the first systematic and meta-analysis review that aims to critically assess and compare the agreement of QuantiFERON-TB Gold In-Tube (QFT-GIT) and Tuberculin Skin Testing (TST) among adults of high-risk groups in Saudi Arabia and compare results with other sites of the Middle East.</p><p>Methodology: Kappa estimates were meta-analyzed using random effect model and several subgroup analyzes were performed to explain overall heterogeneity. Funnel plot, Begg’s and Egger’s tests were employed to assess overall publication bias.</p><p>Results: 18 studies were meta-analyzed, comprising 5070 adults of high-risk groups. Pooled kappa estimates from Saudi Arabia (κ = 0.29, 95% CI: 0.16, 0.41) showed lower rate of agreement compared to other sites of the Middle East (κ = 0.33, 95% CI: 0.25, 0.41). However, a significant level of heterogeneity (<em>I<sup>2</sup></em> = 96.7%, p &gt; 0.001) were identified across collected evidence. Begg’s and Egger’s tests confirmed absence of significant publication bias in this review (p = 0.49 and p = 0.16, respectively).</p><p>Conclusion: This work revealed fair to poor agreement between TST and QFT-GIT, indicating that these two tests are not interchangeable in such settings. Substantial evidence is still needed before considering the sole use of QFT-GIT as an alternative to TST in these populations. Moreover, there is an urgent need for longitudinal studies in Saudi Arabia and the Middle East to accurately assess precision of LTBI diagnosis.</p> ER -
