Cost-effectiveness of preventive treatment regimens for latent tuberculosis infection among key community-level populations.

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
backgroundExpanding tuberculosis preventive treatment (TPT) for high-risk populations with latent tuberculosis infection (LTBI) is a key component of the End TB Strategy. However, the high-risk population size is small, which may have limited impact on reducing TB incidence. We aimed to evaluate the health impact and cost-effectiveness of expanding TPT to key community-level population
methodsWe developed a dynamic transmission model incorporating the effect of TPT and seasonal variations in TB incidence. The model was calibrated by monthly pulmonary tuberculosis (PTB) case data during 2011-2018 from Shaanxi province, China, and validated by data in 2019. We first assessed the TB epidemic trend for seven expanding TPT strategies and sought the optimal TPT strategy that can reach the target of the End TB Strategy by 2035. Then, we calculated the incremental cost-effectiveness ratios (ICER) of this optimal TPT strategy with five TPT regimens (isoniazid monotherapy with two different durations, rifampin monotherapy, and combinations of isoniazid with rifampin or rifapentine) over 2025-2050, compared with no TPT, from a health system perspective. A willingness-to-pay threshold of US $36,378 (three times the per-capita gross domestic product of Shaanxi province in 2023) was used.
resultsThe optimal TPT strategy is implementing TPT for all WHO-recommended populations and individuals with LTBI aged ≥ 50 at the community level (starting in 2025 with full coverage within 1 year), which could reduce the PTB incidence rate to 1.83/100,000 by 2035, meeting the WHO target of a 90% reduction (5.64/100,000) compared with 2015. This strategy with five TPT regimens was all cost-effective compared with no TPT, with ICER ranging from US $154 (3 months of daily rifampicin plus isoniazid, 3HR) to US $910 (9 months of daily isoniazid monotherapy, 9H) per quality-adjusted life-year (QALY) gained.
conclusionsRapid TPT implementation for all WHO-recommended populations and individuals with LTBI aged ≥ 50 at the community level is critical to achieving TB elimination by 2035. The 3HR regimen, widely performed in clinical practice in China, offers the greatest cost-effectiveness, which provides health economic evidence to expand this regimen further.
