TABLE 2.

Bronchodilator responses in spirometry with the highest reversibility chosen from each steroid-naïve asthma patient (N=219)

Mean±sd Median (IQR) Patients
ΔFEV1, mL 294±270 230 (130–400) 219
ΔFVC, mL 210±354 130 (30–300) 219
ΔFEV1, % of the initial FEV1 11.6±10.7 9.5 (4.8–15.3) 219
ΔFVC, % of the initial FVC 6.6±10.9 3.7 (0.8–8.5) 219
ΔFEV1, % of the predicted FEV1 8.3±7.2 7.0 (3.9–10.8) 219

IQR: interquartile range; FEV1: forced expiratory volume in 1 s; FVC: forced vital capacity. The data are not normally distributed. The mean values are shown to make it easier to compare results with other studies.
