  1. ORs, 95% CI and p values were calculated by logistic regression per interquartile range (IQR) increase in air pollutants concentrations (PM2.5: 4.86 μg/m3, NO2: 12.62 μg/m3).
  2. In bold: ORs with p values <0.05
  3. #Multivariate model: Adjusted to age, sex, urinary iodine, BMI, education level, smoking status and ambient temperature
  4. PM2.5 Particles with an aerodynamic diameter of less than 2.5 microns, NO2 nitrogen dioxide
