Data are presented as mean ± SD except as otherwise noted. HRCT, high-resolution computed tomography. No, number and BP, bronchopulmonary.

^aD-value, difference value, the difference between baseline and 4–6 months later.

^bThe p-value of the d-value between two groups.

^cThere were statistical differences between two groups during exacerbation (p < 0.05), the p-values of others were more than 0.05.

^dThere were statistical differences between two groups 4–6 months later (p < 0.05), the p-values of others were more than 0.05.
