Resident Odor Reports and Differing Health Outcomes in Areas of Industrial Emission Odor, Louisville, Kentucky.
Article in medRxiv : the preprint server for health sciences, 2025. 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
Background: Environmental odors can impact health and risk perception. Participatory, or citizen science, can provide important data through systematic, mobile application assisted odor reporting. Objectives: This study leverages participatory public health science using the Smell MyCity app to investigate resident-reported odors and their association with health outcomes in Louisville, KY. Methods: We analyzed 6,868 odor reports from 2018 to 2024, to identify census tracts where industrial and chemical odor reports cluster. Disease prevalence from the CDC's PLACES data were compared between these tracts and the entire county. Results: Results suggest associations between frequent odor reporting areas and increased health risks, highlighting the public health significance of environmental odors and the importance of community-driven data collection. Conclusions: This community-driven reporting initiative may be a useful addition to health research in areas which also have high industrial emission odor.
