Emphysema 599 (63.0) 352 (37.0) 231 (24.3) 121 (12.7)
  Centrilobular 723 (76.0) 228 (24.0) 105 (11.0) 123 (13.0)

  1. *The changes were considered as subnormal if the radiologic score was < 1 (< 2 in emphysema sum score).
  2. The changes were considered as pathological if the radiologic score ≥ 1 (≥ 2 in emphysema sum score).
  3. The sum score of all emphysematous changes.
