PredictorsOR (95% CI)p-value
ACQ scores3.31 (1.23–8.90)0.018
ΔFeNO (diurnal)1.39 (1.17–1.65)<0.001
PEF (min/max %)0.94 (0.89–0.99)0.015
FEV1 % predicted0.99 (0.94–1.04)0.62

  • ACQ: asthma control questionnaire; FeNO: exhaled nitric oxide fraction; ΔFeNO: change in FeNO; PEF: peak expiratory flow; min/max %: minimum as a percentage of maximum; FEV1: forced expiratory volume in 1 s.
