Quantification of the Spatial Variation and Source Contributions to Ambient Particle-Bound PAHs Using Aerosol Mass Spectrometry.
Article in Aerosol and air quality research, 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
Polycyclic Aromatic Hydrocarbons (PAHs), a subset of air toxics, pose severe health risks even at low concentrations due to their carcinogenic and reproductive effects. Despite their significance, spatial distribution studies of PAHs remain limited, largely due to the absence of real-time, chemically specific methods. This study applies high-resolution aerosol mass spectrometry (AMS) for quantification and spatial analysis of particle-phase PAHs. Laboratory experiments were conducted with four PAH standards (anthracene, pyrene, 9-methyl anthracene, and acenaphthylene) to determine their mass spectra and ionization efficiency. AMS mass spectra of the PAH standards were highly correlated with NIST reference spectra (R Graphical Abstract: Supplementary Information: The online version contains supplementary material available at 10.1007/s44408-026-00109-2.
