Assessment of two methods of measuring airway response to allergen challenge showed that results obtained using FEV1 correlated well with those obtained using sGaw irrespective of pre-treatment. Significantly smaller amounts of allergen were required to reduce the sGaw by 35% than to reduce the FEV1 by 20%, although both indices discriminated equally well between the effects of drugs on airway responses to challenge.
