  1. * Coefficients correspond to a change in the ln IL-8 or lung function for a change in one unit of the FVI or MDI.
  2. † [ln IL-8] model included the following variables: same day exposure: 24-hr average O3 (pbb), gender, body mass index, calories, previous day minimum temperature, corticoid use and chronological time.
  3. ‡ Models for lung function included the following variables: 5-day accumulated moving average O3 (ppb), gender, body mass index, calories, previous day minimum temperature and chronological time.
