  1. Eo: Eosinophil. FEV1: forced expiratory volume in 1 s. FEV1%: the ratio of forced expiratory volume in is (FEV1) to forced vital capacity (FVC). RT-Meth: respiratory threshold of methacholine (mg/ml) required to cause a 20% or more fall in FEV1 from the baseline value. Cough: The capsaicin cough threshold (C5) was defined as the lowest concentration of inhaled capsaicin eliciting five or more coughs.
