Correlations of FeNO with eosinophils in sputum. The FeNO and eosinophils in sputum were positively correlated in patients with CARAS initially presenting with AR, patients with CARAS initially presenting with asthma and patients with AR only (r=0.62, 0.70, and 0.76, respectively; all P<0.05). CARAS-AR, patients with CARAS initially presenting with AR; CARAS-AS, patients with CARAS initially presenting with asthma; AR, allergic rhinitis; Eos, eosinophils; CARAS, combined allergic rhinitis and asthma syndrome; FeNO, fractional exhaled nitric oxide.
