Assessment of cat exposure to phthalates through phthalate metabolites analysis in the hair samples.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Phthalates are substances used in industry which are harmful to humans and animals. Cats and dogs, living in close proximity to humans, are particularly exposed to the effects of phthalates. Although hair samples seem to be the best matrix for studies on long-term exposure to phthalates, no such studies have been conducted in cats to date. This study aimed to establish concentration levels of selected phthalate metabolites (i.e. monomethyl phthalate-MMP, monoethyl phthalate-MEP, mono-isobutyl phthalate-MiBP, monobutyl phthalate-MBP, monobenzyl phthalate-MBzP, mono-cyclohexyl phthalate-MCHP and mono(2-ethylhexyl) phthalate-MEHP) in cat hair samples using liquid chromatography with mass spectrometry (LC-MS/MS) analysis. MiBP and MEHP were found in 100% of samples with median 66.6 pg/mg and 35.9 pg/mg, respectively, MBP in 97.1% with median 55.7 pg/mg, MEP in 94.3% with median 152.0 pg/mg, MMP in 85.7% with median < limit of quantification (LOQ) and MBzP in 32.9% with median < limit of detection (LOD). MCHP has not been found in cat hair samples during this study. The study has shown that cats are exposed to phthalates. This exposure is higher in indoor cats and depends on the body condition. On the other hand, statistically significant gender- and age-dependent differences in phthalate metabolites levels have not been found during this study. The results have also shown that hair samples may be used as a matrix during studies on levels of phthalate metabolites in cats.
