Assessment of Bisphenol A (BPA) Exposure in Dairy Cows Using Hair Samples Analysis.
Article in Animals : an open access journal from MDPI, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Bisphenol A (BPA) is a plasticizer known to have various adverse effects on humans and animals. Exposure of farm animals to BPA negatively impacts their health and poses a threat to humans who consume products of animal origin. Despite the importance of studying the exposure of farm animals to BPA, the knowledge in this area is quite limited. To date, the assessment of BPA levels in dairy cows using analysis of hair samples has not been performed. The study utilized liquid chromatography-mass spectrometry to analyze hair samples collected from 48 dairy cows in the following regions of Kyrgyzstan: Sokuluk, Alamedin and Ysyk Ata. BPA levels above the limit of detection (LOD = 4.8 pg/mg) were noted in 18.8% of analyzed samples. BPA levels in individual samples ranged from below LOD to 89.1 pg/mg with a median value of 9.3 ± 19.7 pg/mg. The study indicates that dairy cows are exposed to BPA, and hair samples can be used for BPA biomonitoring in farm animals. The present study is the first investigation of BPA levels in cows' hair, which is one of the best matrices to study long-term exposure of living organisms to environmental pollutants. Additionally, this study is the first to analyze BPA in biological samples from Kyrgyzstan.
