  1. Time Lags = Time intervals of exposures studied (Mean 2 days = average of the same day and previous day; Mean 5 days = mean of the same day and the previous four days; Night = average between 23:00- 07:00). N obs = number of observations present for exposure and symptoms. N differs because of missing values in exposure and symptom reporting. BrC measured at two of four sites. N cases = number of participant-days reporting the symptom. OR Odds ratio, LCI Lower confidence interval limit, UCI Upper confidence interval limit, Associations adjusted for temperature, relative humidity, pollen count and duration of study participation
  2. aSmaller N because measured in two towns only
  3. bSmaller N is due to missing exposure data
