  1. The model was adjusted for age at first visit (years), height (cm), gender, education, COPD medications use, smoking status at first visit, pack-years and time since first visit (years)
  2. β; 95% CI in parentheses (all such values)
  3. Abbreviations: FEV1 forced expiratory volume in 1 s, FVC forced vital capacity, PMA pectoralis muscle area, PMD pectoralis muscle density
