- Age, BMI and lung function measures were recorded at the screening visit. Methacholine FeNO and PC20, which were not recorded at the screening visit, are based on average pre-exposure values for all the exposures. PC20 > 16 are considered normally responsive according to the European Respiratory Society Technical Standard
- BMI, body-mass index; FeNO, fractional exhaled nitric oxide; FEV1, forced expiratory volume in 1Â s; FVC, forced vital capacity; PC20, methacholine provocation concentration causing a 20% drop in FEV1
