Systematic Review of Contact Investigation Costs for Tuberculosis, United States.
Synthesis in Emerging infectious diseases, 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
Contact investigation is a fundamental component of tuberculosis (TB) programs that drives prompt diagnosis and treatment of Mycobacterium tuberculosis infection among those exposed. Few studies have examined contact investigation costs for TB. We conducted a systematic review of TB contact investigation costs in the United States by searching English-language articles published during January 1990-August 2024 in electronic databases, including MEDLINE, Embase, CINAHL, and Scopus. We identified 2,920 titles and abstracts; 10 studies met our inclusion criteria. We abstracted costs for labor, diagnostic tests, and chest radiographs. Labor cost per contact was estimated at $175.94 (range $79.97-$293.51); total cost, including diagnostic testing and chest radiography, was $228.93 (range $132.95-$346.49).The overall cost of contact investigation in the United States was $9.94 (range $5.77-$15.04) million in 2022; total cost during 2013-2022 was $137.35 million. Contact investigations are essential to prevent TB and avert TB-related labor and diagnostic costs.
