Data are presented as n or mean±sd, unless otherwise stated. Statistical comparisons were performed in allergic (groups a, A and R) versus healthy control subjects (group C) and in uncontrolled (group A) versus controlled (group a) asthmatics using unpaired t-tests and the Chi-squared test. PMN: polymorphonuclear cell; FEV1: forced expiratory volume in 1 s; FVC: forced vital capacity; FEF25–75%: forced expiratory flow at 25–75% of FVC; NA: not available. #: p<0.005 for group A versus group a by unpaired t-test.
