TB antigen-based skin tests and QFT-Plus for Mycobacterium tuberculosis infection diagnosis in Brazilian healthcare workers: a cost-effectiveness analysis.
Article in Cadernos de saude publica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
This study aimed to analyze the cost-effectiveness of three tuberculosis (TB) antigen-based skin tests (TBST) (Diaskintest, C-TST, and Cy-TB) and QFT-Plus for TB infection diagnosis compared to the current standard of care, PPD Rt-23 tuberculin skin test (TST), among healthcare workers in Brazil. A state-transition Markov model was employed, simulating a cohort of healthcare workers (five annual cycles) for testing and treating TB infection with three months of weekly doses of rifapentine and isoniazid (3HP) under the Brazilian public health system perspective. Effects (TB disease averted) and costs for screening and treating TB infection were discounted at 5%. Incremental cost-effectiveness per TB averted was estimated. One-way and probabilistic sensitivity analysis were performed. Brazil, an upper-middle-income country with a high burden of TB, shows one of the largest universal public health systems and provides free-of-charge diagnosis and treatment for TB and TB infection. TST is the standard of care, whereas QFT-Plus is available for very high-risk populations. The three new TBST are under validation for eventual incorporation. Patients or participants: a hypothetical cohort of 10,000 healthcare workers, working at any level of healthcare service, and negative TST results in the previous year of both sexes with a baseline negative TST result. Diaskintest, C-TST, Cy-TB, and QFT-Plus were found to show a higher specificity. Costs with QFT-Plus were higher due to equipment, human labor, and test price. Diaskintest was the most cost-saving strategy, followed by Cy-TB for TB preventive treatment with 3HP. In the Brazilian scenario, Diaskintest and Cy-TB are the most cost-effective tests for sequential testing of healthcare workers.
