There were significant differences in the DLCO% and TLC% between the treatment group compared to the control group at the end of the study (P < 0.05, respectively, a and b). However, there were no significant differences between the two groups in terms of other pulmonary function tests, including FVC and DLCO/VA, both during the 6-month treatment period and the 18-month follow-up period (c and d). [DLCO% (control group vs. treatment group): 67.12 ± 14.72 vs. 69.19 ± 19.83, p = 0.732 (at 3 months); 70.83 ± 14.62 vs. 74.91 ± 14.80, p = 0.465 (at 6 months); 64.67 ± 16.22 vs. 80.87 ± 19.40, p = 0.027 (at 24 months)]. [TLC% (control group vs. treatment group): 74.09 ± 11.37 vs. 73.12 ± 15.29, p = 0.836 (at 3 months); 74.28 ± 11.18 vs. 78.48 ± 8.88, p = 0.269 (at 6 months); 70.97 ± 10.79 vs. 79.77 ± 7.76, p = 0.010 (at 24 months)]
