[A–D] Comparison of the cavitary lesion (A), modified Reiff score (B), number of affected lobes (C), and the 6-min walk distance (D) among the normal bone mineral density (BMD), osteopenia, and osteoporosis groups. E Percentage of low serum estradiol (E₂) levels (< 10 pg/mL) stratified by age in female patients with nontuberculous mycobacterial pulmonary disease. F T-score compared between low serum E₂ and others. G Comparison of low serum E₂ status among normal bone mineral density (BMD), osteopenia, and osteoporosis groups. H Serum 25OHD levels represented as a continuous variable among normal bone mineral density (BMD), osteopenia, and osteoporosis groups. **P < 0.01. ***P < 0.001
