Impact of Chemical Composition on Aerosol Scattering: Insights from the Surface Particulate Matter Network and Aerosol Robotic Network.
Article in Environmental science & technology, 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
Using the Surface Particulate Matter Network (SPARTAN) and Aerosol Robotic Network (AERONET), we investigated the relationship between aerosol chemical composition and optical properties across 14 global sites. The mass concentrations of ammonium sulfate (AS), ammonium nitrate (AN), fine soil (FS), and black carbon (BC) from SPARTAN were collocated with aerosol optical properties (aerosol optical depth (AOD), fine mode fraction (FMF), and single scattering albedo (SSA)) from AERONET. Significant differences in the optical properties of samples from 2016 to 2023 were identified based on the mass and mass ratios of the chemical components. For the BC-FS relationship in the data set used in this study, increased FS mass lowered FMF and dSSA
