Chemical exposure
Phthalates, thyroid hormones, and adult blood lipids

In 222 Taiwanese adults, urinary phthalate metabolites tracked with thyroid hormones and lipid markers; T4 appeared to sit on the path from DEHP metabolites to HDL-C, but that mediation interval included the null.

Phthalates, thyroid hormones, and adult blood lipids
These passages occur verbatim in the stored paper text. They support the points listed below; they do not verify every statement in the explanation.
What did MEP associate with?
MEP exhibited negative association with TC and NHC
Did the authors still interpret thyroid hormones as mediators?
Our findings supported that thyroid hormones mediate the association between phthalate exposure and lipid metabolism.
Key findings
MMP associated with lower LDL-C; MEP with lower total cholesterol; ΣDEHP metabolites with higher HDL-C. T4 was estimated to mediate 32.2% of the ΣDEHPm–HDL-C link, but that indirect effect was not statistically significant.
Methodology
Authors measured nine urinary phthalate metabolites, thyroid hormones (including T4 and TBG), and fasting lipids in 222 adults, then used regression and mediation analysis (plus BKMR mixtures) to test whether thyroid function links phthalates to lipids.
Limitations
Cross-sectional mediation cannot establish that phthalates change lipids via thyroid hormones; the headline T4 path was not significant and the sample is modest.
