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 a major global health challenge, particularly in polluted areas. The relationship between ambient particulate matter and TB risk remains unclear, making this systematic review and meta-analysis (SRMA) vital for assessing this link. This SRMA aimed to estimate the association between exposure to ambient particulate matter (PM10 and PM2.5) and the risk of pulmonary tuberculosis (PTB) infection. A literature search was conducted in PubMed, Web of Science, and Cochrane (English-language studies) on January 29, 2024. The review followed PRISMA Guidelines (2020) for comprehensive literature searches, data extraction, and quality assessment of included studies. A random-effects model was used for meta-analysis to estimate pooled effect sizes and assess heterogeneity. Study quality and publication bias were also evaluated. Of the 507 articles identified, 25 met the inclusion criteria. Long-term PM2.5 exposure was linked to a 26% increase in PTB risk (RR =1.26, 95% CI: 1.07-1.48), while short-term exposure raised the risk by 10% (RR =1.10, 95% CI: 0.98-1.25). Long-term PM10 exposure increased PTB risk by 7% (RR =1.07, 95% CI: 1.02-1.12), with short-term exposure showing a similar increase (RR =1.07, 95% CI: 0.95-1.17). Subgroup analysis revealed PTB risk increased by 15% in males and 29% in females for PM2.5, and by 10% in males and 7% in females for PM10. A 10 µg/m³ increase in Particulate matter is associated with a higher risk of pulmonary tuberculosis, highlighting the need for targeted public health measures to reduce particulate exposure, especially in high-risk urban and industrial areas.
