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
This study investigated the prevalence of childhood asthma and respiratory symptoms with their associated air pollution sources among adolescents aged 13-14 years residing in a Malaria-endemic region.
methodsA cross-sectional survey was conducted with 2855 adolescents from fourteen (14) selected schools in communities exposed to high levels of air pollution from indoor residual spraying (IRS) that is used for malaria vector control in the Vhembe region. Data were collected using a self-administered standardized International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. Statistical software STATA version 17 was used to analyze the data. Binary logistic regression was used to determine the relationship between air pollution sources and childhood asthma/symptoms.
resultsThe prevalences of asthma, 'wheeze ever' and 'wheeze in the past' were 18.91%, 37.69% and 24.69%, respectively. The results from the adjusted binary logistic regression model indicated that exposure to tobacco smoke (OR = 1.84; 95% CI: 1.08-3.16), smoking a water pipe (OR = 1.65; 95% CI: 1.16-2.36) and the use of paraffin as fuel for heating (OR = 1.70; 95% CI: 0.97-2.88) and cooking (OR = 0.48; 95% CI: 0.29-1.00) were significant risk factors for asthma. Trucks passing through the streets, having a cat at home and using open fires were significantly associated with 'wheeze in the past'. Finally, using gas for cooking (OR = 0.72; 95% CI: 0.53-0.99), open fires for heating (OR = 0.53; 95% CI: 0.35-0.80) and smoking a water pipe (OR = 2.47; 95% CI: 1.78-3.44) were associated with 'wheeze ever'.
conclusionsSchool children living in these communities had an increased risk of developing asthma and presenting with wheezing due to exposure to environmental air pollution sources.
