Association between ambient particulate matter and respiratory health among schoolchildren in Dar es Salaam city, Tanzania: a cross-sectional study.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundUrbanization and industrial activities have significantly contributed to the deterioration of air quality, with ambient particulate matter (PM
objectiveThis study aimed to determine the level of ambient particulate matter (PM
methodsWe conducted a cross-sectional study targeting schoolchildren aged 9-16 to investigate the impact of air pollution on respiratory health. A sample of 427 children was selected through stratified random sampling, which combined primary and secondary data. Standardized questionnaires and air quality monitoring for PM exposure were used to collect data. Analysis methods included descriptive statistics, and logistic regression to elucidate the association between PM exposure and respiratory symptoms.
resultsThe prevalence of respiratory symptoms among the schoolchildren was notably high, with 35.1% reporting coughing, 26.7% wheezing, 31.4% breathlessness, and 28.1% severe chest illness. Significant associations were found between proximity to pollution sources (OR = 3.4, 95% CI: 2.3-5.0, p < 0.001 for coughing; OR = 7.0, 95% CI: 2.9-17.2, p < 0.001 for wheezing; OR = 3.9, 95% CI: 2.3-6.6, p < 0.001 for breathlessness; OR = 6.4, 95% CI: 3.3-12.0, p < 0.001 for severe chest illness), household smoking (OR = 1.2, 95% CI: 1.02-1.4, p < 0.05 for wheezing; OR = 1.2, 95% CI: 1.01-1.4, p < 0.05 for severe chest illness), and the use of biomass for cooking (OR = 2.4, 95% CI: 1.4-4.0, p < 0.01 for wheezing; OR = 2.3, 95% CI: 1.4-3.8, p < 0.01 for severe chest illness) with the occurrence of respiratory symptoms. Ambient PM levels, particularly PM
conclusionThe study emphasizes the significant impact of air pollution on the respiratory health of schoolchildren in Dar es Salaam and calls for targeted interventions to reduce particulate matter exposure, particularly in high-risk urban areas of Dar es salaam, Tanzania.
