Table 2 Correlation between % emphysema at screening with measurements of ventilation and lung function (intra-individual difference between indacaterol/glycopyrronium and placebo)
From: Effect of indacaterol/glycopyrronium on ventilation and perfusion in COPD: a randomized trial
Parameter 1 | Parameter 2 | r2 value |
|---|---|---|
Percentage ventilated lung volume at Day 7 | Extent of emphysema at screening (%) | 0.08 |
Inspiratory capacity at Day 8 (L) | Extent of emphysema at screening (%) | 0.08 |
Forced expiratory volume in 1Â s on Day 8 (L)a | Extent of emphysema at screening (%) | 0.02 |
