LAA% = percentage ratio of low attenuation area to the lung area; i = inner segment; o = outer segment; T = total three sections; U = upper lung; M = middle lung; L = lower lung; NS = not significant; VC = vital capacity; TLC = total lung capacity; RV = residual volume; FEV1 = forced expiratory volume in one second; FVC = forced vital capacity; Tlco = carbon monoxide transfer factor; VA = alveolar volume.
