Comparisons of computed tomography characteristics among the five lung lobes in 157 male smokers.

Data are presented as medians (25th, 75th percentiles). LAV, low attenuation volume at the threshold level of −950 Hounsfield units; √Aaw at Pi10, square root of airway wall area of the hypothetical airway with an internal perimeter of 10 mm.*data from 146 subjects.†P2 = 0.78).‡P2 = 0.75).数据以中位数（第25、75百分位数）表示。低衰减体积（low attenuation volume, LAV）：阈值为-950亨氏单位（Hounsfield Unit, HU）时的检测指标；Pi10处的√Aaw：指内部周长为10 mm的假想气道的气道壁面积的平方根。*数据来自146名受试者。†P2=0.78）。‡P2=0.75）。
