(a) Percent predicted forced expiratory volume in 1 second (FEV1) by control status at Week 12 (mean and 95% confidence interval) and (b) Change in percent predicted FEV1 from baseline to Week 52 by control status at Week 52 (mean and 95% confidence interval). Patients with TC asthma has significantly higher FEV1 % predicted compared to those with NTC asthma, and WC patients had significantly higher FEV1 % predicted compared to those NWC. Key: TC: Patients with totally controlled asthma. NTC: Patients with well controlled or not well controlled asthma. WC: Patients with either well controlled or totally controlled asthma. NWC: Patients with not well controlled asthma. Figures in brackets are number of patients per group.
