In patients with chronic obstructive pulmonary disease (COPD), pulmonary rehabilitation (PR) confers significant, clinically relevant benefits upon anxiety and depression symptoms, a new study found. The systematic review and meta-analysis was conducted according to PRISMA guidelines on randomized controlled trials comparing PR (≥4 weeks duration) to usual care. Researchers found:
- 11 studies comprising 734 participants were included.
- Compared with usual care, PR conferred significant benefits of a moderate magnitude for anxiety symptoms and large magnitude for depression symptoms.
- The certainty of evidence for each outcome was moderate.
