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
Background: The quality of air in kindergartens, where children spend a significant part of their time, is an important determinant of health. Objective: This study aimed to explore the relationship between indoor air pollution in kindergartens and wheezing syndrome in preschool children. Methods: Air pollution, specifically the concentration of particulate matter (PM), was measured in 24 kindergartens. A total of 1,794 parents of preschool children were surveyed about respiratory symptoms and environmental factors affecting their children. Results: The mean age of the children was 4.07 (± 1.44) years, and 50.9% were males. Wheezing history was reported in 5.8% of children, while separately evaluated physician-diagnosed bronchiolitis in 11.1% and asthma in 2.6%. One third of children were exposed to smoking and 44.2% had pets at home. Allergic rhinitis and eczema, having siblings, higher concentrations of PM Conclusion: The association between wheezing and indoor PM
