  1. PM10 particulate matter, PM2.5 fine particulate matter, NO2 nitrogen dioxide, CO carbon monoxide, SO2 sulfur dioxide, O3 ozone, CI confidence interval
  2. aRatio of observed AMH to age-specific AMH. Age-specific AMH was calculated from a quadratic model (logAMH = −1.442 + 0.225 × age − 0.004 × age2) from prior study [30]
  3. bAdjusted for body mass index (BMI), working status, previous smoking history, season at the time of testing, and district of residence. Estimates in bold have P values < 0.05
