  1. (according to work-related symptoms and CAP results (CAP class ≥ 1) subjects 1 to 5 were considered as "maize pollen-allergic")
  2. *data were expressed as predicted values (reference values by Brändli et al. (2000))
  3. NS BHR = non-specific bronchial hyperresponsiveness
  4. significant changes of lung function parameters after pollination are bold
  5. n/a = not applicable
