  1. * Coefficients correspond to a change in the ln IL-8, LnFeno, pH or lung function for a change in one unit of the FVI or MDI.
  2. Models for inflammatory markers included 753 inflammatory marker measurements for 119 asthmatic children. Models are adjusted for the following variables: same day exposure: 24-hr average O3 (pbb), 24-hr average PM2.5 (μg/m3), previous day minimum temperature, gender, body mass index, calories, corticoid use and chronological time.
  3. Models for lung function included 1503 lung function measurements for 158 asthmatic children.
  4. Models are adjusted for the following variables: 5-day accumulated moving average O3 (ppb), 5-day accumulated average (maximum) PM2.5 (μg/m3), previous day minimum temperature, gender, body mass index, calories and chronological time.
  5. &p value of interaction between ozone and indices (FVI or MDI)
