TBI; traction bronchiectasis/bronchiolectasis index.

Age and BMI are described as mean ± standard deviation [range], while Pack-year is described as median [range].

^*TB Progression Score 1 (n = 4) and Score 2 (n = 2) are included in Score 3 (n = 130) due to small number of cases.

^†P value is for the comparison among all groups by one-way analysis of variance.

^‡P value is for the comparison among all groups by Chi-squared test.
