  1. Participants were matched using propensity score matching with age, sex, BMI, marital status, smoking status, education, regular muscle exercise, FEV1, FVC, and FEV1/FVC. Values are expressed as weight percentage. The* p-value < 0.05 indicates significant difference between two groupswas calculated using the design-based t-test
  2. TB, tuberculosis; BMI, body mass index; FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity; HTN, hypertension; DM, diabetes mellitus
