Neighborhood-scale disparities in air exchange rates and inhaled pollution dose among school-aged children.
Article in Journal of exposure science & environmental epidemiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAmbient air pollution and its infiltration into indoor environments can vary substantially within urban neighborhoods due to differences in traffic density, emission sources, and housing conditions; however, this variability is often not captured in exposure studies.
objectiveThis study estimates average daily inhaled dose of particulate matter (PM
methodsA hyperlocal network of 84 air quality monitors was combined with parcel-level housing data and the Lawrence Berkeley National Laboratory (LBNL) infiltration model to estimate residential air exchange rates (AERs) and daily inhaled doses of PM
resultsAcross the city, average O SIGNIFICANCE: The combination of parcel-level data and high-resolution monitoring revealed disparities in ambient concentrations, housing conditions, and inhaled dose that could meaningfully influence health outcomes in children. IMPACT: This study utilizes a hyperlocal air quality monitoring network and parcel-level housing data to evaluate air pollution exposure in elementary school-aged children, finding neighborhood-level differences in ambient concentrations and inhaled dose sufficient to influence health outcomes. Air exchange rates varied across the study area and increased in block groups with larger Hispanic/Latino populations and higher rent burdens. This work demonstrates the importance of using high-resolution, microscale air pollution monitors, and individual housing characteristics in exposure studies.
