Figure 2From: Lung clearance index in adults with non-cystic fibrosis bronchiectasisCorrelations between lung clearance index and FEV 1 (% predicted). Correlations are shown for patients with non-cystic fibrosis bronchiectasis (Panel A) and cystic fibrosis (Panel B). LCI = lung clearance index; FEV1 = forced expiratory volume in one second. Best-fit linear regression lines are shown, together with Pearson correlation coefficients.Back to article page
