Per- and Polyfluoroalkyl Substance Levels in Commercial and Home-Produced Eggs in Croatia.

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
The aim of this study was to measure per- and polyfluoroalkyl substance (PFAS) levels in eggs collected in Croatia and to identify differences between commercially produced eggs (cage, barn, and organic) and home-produced eggs (HPE). Thirty PFAS compounds were analyzed using high-performance liquid chromatography coupled with high-resolution mass spectrometry. In HPE, the highest detection frequencies above the limit of quantification were observed for perfluorooctane sulfonic acid (PFOS) at 67.6%, perfluorononanoic acid (PFNA) at 43.2%, perfluoro-n-decanoic acid (PFDA) at 43.2%, and perfluoro-n-dodecanoic acid (PFDoDA) at 35.8%. Perfluorooctanoic acid (PFOA) was detected only in HPE. Furthermore, HPE exhibited significantly higher mean lower bound (LB) and upper bound (UB) levels for all measured compounds, as well as for the sum of the four main PFAS (∑4PFAS: PFOS, PFOA, PFNA, and perfluorohexane sulfonic acid [PFHxS]), with values of 0.263 and 0.44 µg/kg, respectively. Cage eggs showed the lowest LB and UB levels. The dietary contribution of ∑4PFAS to the established tolerable weekly intake (TWI) limit of 4.4 ng/kg bw indicated that children up to nine years old are the most vulnerable to exposure, particularly infants and toddlers consuming HPE. Significantly lower exposure was observed with cage eggs; therefore, consumers are advised to prefer these eggs.
