  1. PEF peak expiratory flow, FEV1 forced expiratory volume in 1 s, NO nitrogen oxide, ECP eosinophil cationic protein, MPO myeloperoxidase, IL interleukin, IFN interferon
  2. aNasal lavage was not performed on the students
  3. bPEF and FEV1 are the mean of repeated measurements ± the standard deviation (SD) made during a 2-week period
