Air Pollutants Associated Hospitalization in Pediatric Pneumonia: A National Database Analysis.
Observational study in Pediatric pulmonology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundPneumonia ranks as a leading contributor to hospital admissions and mortality among children worldwide. This study aimed to investigate the association between aerosol components of air pollution and pediatric pneumonia hospitalization.
methodsEmploying an observational study design, data from hospitalized children under 15 years diagnosed with pneumonia in Thailand from 2015 to 2019 were analyzed to ascertain the relationship between air pollution and health outcomes. Utilizing the Modern-Era Retrospective analysis for Research and Application version 2 (MERRA-2) data for aerosol components, and adjusting for demographic and geographical factors, using Poisson regression models.
resultsA total of 732,700 children were hospitalized with pneumonia, with children under the age of five accounting for the majority of admissions (637,313 cases, 86.9%). Dust had the strongest association with the incidence rate ratio of hospitalization in children with pneumonia across all age groups. The incidence rate ratio was 1.288 (95% CI: 1.271-1.304, p < 0.001), 1.392 (95%CI: 1.344-1.442, p < 0.001), and 1.349 (95%CI: 1.265-1.439, p < 0.001) for children under the age of 5, 5 to under 10, and 10 to under 15, respectively. The association of hospitalization among children with pneumonia increased by 21.0% and 13.8% for each 1 μg/m3 increase in black carbon and dust levels, respectively.
conclusionThe findings reveal a compelling link between certain air pollutants and pediatric pneumonia hospitalization, highlighting the urgent need for targeted interventions to mitigate air pollution's adverse effects.
