  1. Bold values are statistically significant
  2. #All measures were adjusted for sex, age, smoking pack-years, and body mass index. LAA%-950, Pi10, and LAA%-856 are also adjusted for total lung volume (inspiratory or expiratory as appropriate)
  3. +Tukey p-value for multiple comparisons adjustment
