Surface-Enhanced Raman Spectroscopy Detection of Per- and Polyfluoroalkyl Substances in Aqueous Film-Forming Foams.
Article in Environmental science & technology, 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
Identifying the presence and identity of per- and polyfluoroalkyl substances (PFAS) in complex mixtures is critical for water treatment, hazardous waste cleanup, and the identification of workplace hazards. The cost and scale of conventional methods for PFAS detection often make rapid and portable detection challenging. Here, we use concave cubic gold nanoparticles for surface-enhanced Raman spectroscopy (SERS) to detect PFAS in parts per million concentrations, differentiating the 6 PFAS─PFHpA, PFNA, PFDA, PFOA, PFHxS, and PFOS─regulated in the Commonwealth of Massachusetts by the Department of Environmental Protection (MassDEP). Calculated Raman spectra, solid-state Raman spectra, and
