Table 1.  Baseline characteristics of patients

Table 2.  Baseline CT parameters of patients

Table 3.  One-year changes in pulmonary function

Table 4.  One-year changes in CT parameters

Figure 1.  Relationship between changes in residual volume (RV) and low attenuation volume (LAV) in the tiotropium-treated patients. Changes in RV and LAV (ρ = 0.45, p = 0.01) were significantly correlated.
