Air pollution and hospitalization risk in infants with bronchiolitis: A systematic review and meta-analysis.

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
Bronchiolitis is one of the leading causes of hospitalization among infants. Established risk factors include young age, prematurity, and exposure to tobacco smoke. Emerging evidence suggests that air pollution may also contribute to the burden of respiratory diseases. However, its link with bronchiolitis hospitalizations remains debated. To address this, we conducted a systematic review and meta-analysis to assess whether exposure to air pollutants is associated with an increased risk of hospitalization for bronchiolitis in infants. A systematic review and meta-analysis were conducted following the PRISMA guidelines. PubMed, Embase, and Web of Science were searched up to May 2024. Eligible studies examined the relationship between air pollutants and bronchiolitis hospitalizations in infants up to 2 years of age. Meta-analyses were performed to estimate the association between pollutant levels and hospitalization risk. Out of 788 identified studies, 23 met the inclusion criteria. Studies were heterogeneous regarding design, adjustment for confounders, and statistical approaches. Particulate matter with diameter ≤2.5 μm (PM
