Vaping and Tuberculosis: An Overlooked Risk in High-Burden South Asian Countries.
Article in Public health challenges, 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
Tuberculosis (TB) is an infectious disease that remains one of the most pressing threats to public health, especially in South Asian countries. Despite being curable, it is a major cause of morbidity and mortality, driven by factors such as poverty, lack of nutrition, HIV infection, and overcrowding of individuals. Among modifiable risk factors, tobacco smoking has long been established as a major contributor to TB incidence. However, the increasing use of vapes/e-cigarettes, perceived as a safer alternative to traditional smoking, can pose as an underrecognized threat to TB control, particularly in high-burden regions. Vaping exposes individuals to nicotine, flavoring agents, and toxic substances that compromise lung immunity. Evidence shows that vaping impairs alveolar macrophage function, reduces cytokine signaling, and suppresses defense peptides in the host. All of these factors enhance
