Analysis of sources and sinks of indoor particulate matter reveals insights into the real-world efficacy of portable air cleaners in a randomized intervention trial.
Trial report in The Science of the total environment, 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
The increasing availability and accuracy of consumer-grade air quality sensors have increased the spatiotemporal scales at which indoor exposure measurements can be conducted. Here, we develop and apply an analytical framework, based on mass balance principles and open-source signal processing tools, to characterize sources and sinks from time-resolved data in an ongoing randomized parallel-group intervention trial of portable air cleaners (PACs) with high-efficiency particulate air (HEPA) filters in homes in metropolitan Chicago, Illinois USA. Low-cost sensors measured fine particulate matter (PM
