Definition of abbreviations:
Af(+)/IgE(+): Aspergillus fumigatus hypersensitivity with elevated serum total IgE.
Af(−)/IgE(+): no Aspergillus fumigatus hypersensitivity but with elevated serum total IgE.
Af(−)/IgE(−): no Aspergillus fumigatus hypersensitivity with normal serum total IgE.
FEV1: Forced expiratory volume in 1 second, FVC: Forced vital capacity.
