AUC(0,0.5 h) (index of pulmonary absorption) (95% confidence intervals) for formoterol and B17MP following inhalation of the extrafine fixed (BDP/FF pMDI) combination (A) and following inhalation of the extrafine fixed combination (BDP/FF pMDI) with VHC (B), in two groups of asthmatic adolescents: patients with poor inhalation technique (low50th percentile) and patients with good inhalation technique (high 50th percentile). Differences were considered significant at P < 0.05; _****, P < 0.0001; NS, not significant
