  1. aThere were 166 distinct dates when infants were clinically assessed. n refers to the number of distinct dates when infants were clinically assessed that each weather aspect and air pollutant were available due to missing data from the Bureau of Meteorology or New South Wales Air Quality Monitoring Network
  2. bNegative values are reported due to the accuracy limitations of the measuring instrument
  3. CO Carbon monoxide, eNO exhaled nitric oxide, NH3 ammonia, NO Nitric oxide, NO2 Nitrogen dioxide, O3 Ozone, PM10 Particulate matter less than 10 μm, PM2.5 particulate matter less than 2.5 μm, SO2 Sulfur dioxide
