TB yields from expanded contact tracing investigations.
Review in Public health action, 2025. 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
backgroundTB poses a significant global health challenge due to a substantial case-detection gap. Traditional contact tracing primarily targets contacts of bacteriologically confirmed pulmonary TB index patients, often excluding pediatric, clinically diagnosed, and extrapulmonary cases. This review assessed the potential of expanding contact tracing to these frequently overlooked subgroups.
methodsWe conducted a focused, targeted literature review by searching PubMed, Web of Science, Google Scholar and Lens.org using identified keywords. A title and abstract review was conducted using predefined inclusion/exclusion criteria.
resultsWe identified 13 relevant studies reporting contact tracing yields from these index patient groups. Contact tracing of pediatric, clinically diagnosed, and extrapulmonary TB index patients yielded up to 8.1%, 3.0%, and 2.1% for active disease and up to 17.9%, 12.6%, and 11.1% for TB infection, respectively.
conclusionFindings suggest that expanding contact tracing for these typically excluded index patients can improve case detection. By refining contact tracing protocols and adopting more inclusive strategies, TB programs can enhance case detection rates and improve overall disease control efforts, aligning with global goals for TB elimination.
