FEV₁, forced expiratory volume in 1 second; FVC, forced vital capacity; ΔFEV₁, percent change in FEV₁ after bronchodilator inhalation; MChPC₂₀, provocative concentration of methacholine required to a 20% decrease in FEV₁; SE, standard error; BMI, body mass index; LDL-C, low-density lipoprotein cholesterol.

Boldface indicates a statistically significant difference with P<0.05.
