1 · What the graph read from it

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.

2 · The registry

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

Particulate matter (PM) poses a significant public health concern, particularly in industrialized communities. While modern sophisticated air monitors like those deployed by the United States Environmental Protection Agency (US EPA) provide accurate 24-h PM2.5 (PM ≤ 2.5 µm) data, limited spatial and temporal coverage may create monitoring gaps. Low-cost monitors, such as a PurpleAir monitor (PA-II), offer an accessible alternative; however, their accuracy can be influenced by local environmental conditions and PM characteristics. This study evaluated the site-specific performance of PA-II in an industrial region within northern Lake County (N = 6) and a suburban region of Tippecanoe County (N = 4), both in Indiana, United States. As a reference measurement, a deployable particulate sampler (DPS) was co-located with each PA-II. For microscopic analysis, PM was collected on a glass substrate. PA-II data were assessed in raw form and following calibration using two methods, with performance assessed by root mean square error (RMSE) and the coefficient of determination (R Graphical Abstract: Supplementary Information: The online version contains supplementary material available at 10.1007/s44408-026-00112-7.
