  1. Notes:
  2. General Linear Model (GLM) for remission of asthma to persistent asthma. Estimated marginal means used for determination of height adjusted means.
  3. (n) represents number of participants that provided information.
  4. FEV1 = Forced expiratory volume in first second in liters (L) with standard error (S.E.).
  5. FVC = Forced vital capacity in liters (L) with standard error (S.E.).
  6. FEF25–75% = Forced expiratory flow 25 to 75% in liters per second (L/s) with standard error (S.E.).
