Please output the extracted information in JSON format. Do not output anything except for the extracted information. Do not add any clarifying information. Do not add any fields that are not in the schema. If the text contains attributes that do not appear in the schema, please ignore them.

Input:Indacaterol once-daily provides superior efficacy to salmeterol twice-daily in COPD: a 12-week study.  Indacaterol is a novel, inhaled once-daily ultra-long-acting β(2)-agonist for the treatment of COPD. This 12-week randomised, parallel-group study compared the efficacy of indacaterol 150 μg once-daily to salmeterol 50 μg twice-daily in patients with moderate-to-severe COPD. Assessments included FEV(1) standardised area under curve (AUC) from 5 min to 11 h 45 min at Week 12 (primary endpoint), 24-h trough FEV(1) (mean of 23 h 10 min and 23 h 45 min post-dose) at Week 12 (key secondary endpoint), FEV(1) and FVC measured over 24-h, transition dyspnoea index (TDI) and rescue medication use. Of 1123 patients randomised 92.1% completed. Mean ± SD age was 62.8±8.78 years, post-bronchodilator FEV(1) 51.8±12.32% predicted, FEV(1)/FVC 50.6±9.54%. At Week 12, FEV(1) AUC(5 min-11 h 45 min) for indacaterol was statistically superior (p<0.001) to salmeterol (adjusted mean difference [95% CI] 57 [35, 79] mL), as was 24-h trough FEV(1) (60 [37, 83] mL, p<0.001). Indacaterol also showed statistical superiority over salmeterol in terms of FEV(1) and FVC measured over 24-h at Week 12. For TDI at Week 12, the mean total score was statistically superior for indacaterol versus salmeterol (difference 0.63 [0.30, 0.97], p<0.001), as was the percentage of patients with a clinically relevant (i.e., ≥1 point) change from baseline (69.4% vs 62.7%, p<0.05). For rescue medication, patients on indacaterol used fewer puffs/day (difference -0.18 [-0.36, 0.00] puffs/day, p<0.05) and had a greater percentage of days with no rescue use (difference 4.4 [0.6, 8.2], p<0.05). Once-daily indacaterol provided statistically superior bronchodilation with an improvement in breathlessness and rescue use compared with twice-daily salmeterol. ClinicalTrials.gov NCT00821093.
