Association of ambient air pollutant exposure during the 0–90 days prior to thyroid examination and thyroid function. Note: Separate regression models were conducted for square-root transformed TSH and Tg, and for log10-transformed FT3 and FT4. *p < 0.05, **p < 0.01. ***p < 0.001. Models were adjusted for age, education, ethnicity, occupation, income, pre-pregnancy BMI, smoking status, passive smoking status, drinking status, intake of iodized salt, intake of iodine-rich food, average temperature and relative humidity.
