Per- and polyfluoroalkyl substances in commercially important marine species of fish and shellfish from Alaska and implications for human exposure.
Article in Toxicology reports, 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
Per- and polyfluoroalkyl substances (PFAS) are persistent environmental synthetic contaminants associated with some adverse health effects under certain exposure conditions. Dietary sources, particularly seafood, have been identified as a potentially significant contributor to PFAS body burden. Muscle tissue from several species of fish and shellfish harvested in Alaska were analyzed for 40 PFAS analytes. Ten analytes were detected above the method detection limit (MDL) with PFTrDA and PFUnA being the most frequently detected. Concentrations of all analytes ranged from below the detection limit to 0.809 ng/g wet weight with most being below the limit of quantification (LOQ). Overall, PFAS concentrations were low or non-detect, consistent with other market basket studies of seafood. Although no national PFAS-specific fish consumption thresholds are currently established, ongoing surveillance of PFAS in commercially and recreationally harvested seafood provides critical exposure data to inform risk assessment and regulatory decision-making.
