| Age, per 1-year increase | 0.99 (0.95–1.03) | 0.638 | 0.99 (0.94–1.04) | 0.662 |
| Sex: female | 2.59 (0.81–8.58) | 0.107 | 2.47 (0.63–10.22) | 0.194 |
| 3rd-WT/√BSA, per 0.1 mm/mm increase | 1.56 (1.16–2.15) | 0.005 | 1.59 (1.12–2.32) | 0.009 |
| 5th-Ai/BSA, per 1 mm2/mm2 increase | 0.68 (0.48–0.93) | 0.020 | 0.78 (0.53–1.12) | 0.181 |
| %LAA, per 1% increase | 0.92 (0.88–0.96) | <0.001 | 0.92 (0.88–0.96) | <0.001 |
Data are expressed as odds ratios (95% confident intervals). Ai, airway inner luminal area; WT, airway wall thickness; %LAA, percentage of low attenuation area <−950 HU; BSA, body surface area; 3rd-, third generation bronchi, 5th-, fifth generation bronchi.
