  1. Specific IgE was judged as positive when the class was equal to or greater than 1. The sensitivity, specificity, positive predictive value, and negative predictive value for diagnosis of ACO are as follows: Blood eosinophils > 300 μL (44.1%, 76.2%, 60.0%, 62.7%), FeNO > 35 ppb (42.4%, 92.9%, 82.4%, 67.2%), IgE > 100 IU/mL (70.6%, 61.9%, 60.0%, 72.2%), House dust IgE positive (35.3%, 88.1%, 70.6%, 62.7%), D. pteronyssinus IgE positive (35.3%, 88.1%, 70.6%, 62.7%)
