  1. Data are reported as mean ± standard deviation (SD). Data are compared using one-way analysis of variance. p-values are reported for between group comparisons (hospitalized vs. not hospitalized) for males and females separately. BMI, body mass index; Pred of scan TLC, predictive relation lung volume based on the computed tomography scan, absolute measured volume, and predicted total lung capacity.
  2. Significant values are in bold.
