From: Responses of FEV6, FVC, and FET to inhaled bronchodilator in the adult general population

Figure 1

Bland & Altman graphs depicting: a) individual changes in forced vital capacity (FVC) in relation to average FVC, and b) individual changes in forced expiratory time (FET) in relation to average FET, in a bronchodilation test with salbutamol aerosol 0.4 mg in the general adult population (n = 628). The dotted lines indicate the 2 SD limits from the respective mean value. Larger bronchodilation responses in FVC were seen in subjects with lower FVC and larger variation in FET with prolonged FET, which was associated to more severe obstruction.
