Diagnostic performance of third-generation sequencing for tuberculous pericarditis: a systematic review and meta-analysis protocol.
Article in BMJ open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionTuberculous pericarditis is a severe, high-mortality manifestation of extrapulmonary tuberculosis. Its diagnosis is hindered by the invasive nature of specimen collection and the limited sensitivity of conventional microbiological tests. Third-generation sequencing (TGS) offers a promising, rapid and comprehensive molecular approach for detecting METHODS AND ANALYSIS: A protocol has been prospectively registered with PROSPERO. We will comprehensively search multiple databases (PubMed, Embase, Web of Science, SCOPUS, Cochrane Library) from inception to July 2027. We will include diagnostic accuracy studies that evaluate TGS against a composite reference standard for tuberculous pericarditis. Where available, we will also separately analyse studies that use a definitive reference standard. Two independent reviewers will screen records, extract data and assess methodological quality using the QUADAS-2 tool. A bivariate random-effects model will be used to pool sensitivity and specificity, with results summarised using hierarchical summary receiver operating characteristic curves. Heterogeneity will be explored via subgroup analysis and meta-regression. The certainty of evidence will be graded using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. ETHICS AND DISSEMINATION: Given that this investigation exclusively draws on open-source, non-identifiable data, formal institutional ethics clearance is not required. On finalisation, the findings of this systematic review will be disseminated via a suitable peer-reviewed journal. In parallel, every research phase-spanning protocol design to the final report-will rigorously comply with the established methodological standards for systematic reviews and meta-analyses of diagnostic test accuracy. TRIAL REGISTRATION NUMBER: CRD420261429012.
