Comparison of luminal hydraulic diameter (Dh) at TLC (a, b, and c) and FRC scans (d, e, and f) between non-dust-exposed subjects and dust-exposed subjects. Values are presented as mean (CI); *P < 0.05; **P < 0.01; ***P < 0.001. Generation zero is started from trachea. BronInt, bronchus intermedius; Dh, hydraulic diameter; FRC, functional residual capacity; LMB, left main bronchus; RMB, right main bronchus; sLLL, subgrouped left lower lobe; sLUL, subgrouped left upper lobe; sRLL, subgrouped right lower lobe; sRML, subgrouped right middle lobe; sRUL, subgrouped right upper lobe; TLC, Total lung capacity; TriLUL, trifurcation of left upper lobe; TriRUL, trifurcation of right upper lobe
