Phthalate exposure and lipid disruption in Taiwanese children: Insights from serum lipidomic approach.
Article in Journal of food and drug analysis, 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
Phthalates are ubiquitous environmental contaminants that raise particular concern for children, who generally experience higher exposure levels and are more susceptible to environmental pollutants. To understand potential molecular mechanisms, we conducted a cross-sectional study of 256 Taiwanese children aged 8-10 years from two population-based cohorts: the Taiwan Birth Panel Study and the Taiwan Early-Life Cohort. Serum phosphocholine-containing lipids were profiled by liquid chromatography coupled with triple quadrupole mass spectrometry and associated with urinary levels of 12 phthalate metabolites. Multiple linear regression models, adjusted for demographic and socioeconomic factors, revealed that mono-(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP), an oxidative metabolite of di(2-ethylhexyl) phthalate (DEHP), exhibited the strongest associations with lipid alterations. Specifically, higher urinary MEHHP was positively associated with several diacyl-phosphatidylcholines and lyso-phosphatidylcholines, while inversely related to sphingomyelins and ether-linked phosphatidylcholines. These lipid signatures suggest disturbances in lipoprotein metabolism, peroxisome proliferator-activated receptor-related signaling, and sphingolipid balance, offering mechanistic clues to previously observed links between phthalate exposure and hepatic, cardiovascular, and neurological outcomes. Overall, this study identifies lipid perturbations associated with metabolites of DEHP exposure in children and provides molecular insights into how phthalates may disrupt lipid metabolic homeostasis during early life.
