From: Quantitative CT-based structural alterations of segmental airways in cement dust-exposed subjects
Comparison of airway bifurcation angle (θ) at TLC (a) and FRC (b) scans between non-dust-exposed subjects and dust-exposed subjects. Values are presented as mean (CI); *P < 0.05; **P < 0.01; ***P < 0.001. BronInt, bronchus intermedius; FRC, functional residual capacity; LMB, left main bronchus; RMB, right main bronchus; TLC, total lung capacity; TriLUL, trifurcation of left upper lobe; TriRUL, trifurcation of right upper lobe
