- The study examines mucus plugs in COPD and pre-COPD patients using CT scans.
- Patients were categorized into no-, low-, and high-mucus groups based on CT mucus scores.
- High mucus group showed increased odds of sarcopenia, independent of factors like age and emphysema.
- Reduced muscle and fat mass were observed in the high mucus group via BIA and CT.
- 6-minute walk distance was lower in the high mucus group, but physical activity did not differ.
- Increased airtrapping and wall area percentage, and decreased airway count, were noted in high mucus groups.
- No significant difference in emphysema was found across mucus groups.
- Findings suggest mucus plugs are linked to higher sarcopenia risk and reduced body composition.
