It will also negatively influence patients\u2019 outcomes.

Databases including PubMed, Web of Science, Embase, the Cochrane Library, the China Biomedical Literature Service System, China Biomedical Literature Service System (CINAHL), China National Knowledge Infrastructure, the Wanfang database, and the WeiPu (VIP) were systematically searched for cohort studies on muscular atrophy and COPD from inception to July 1st, 2023.

There were seven cohort studies included in the meta-analysis, including 3,458 COPD patients. The meta-analysis showed that patients with COPD combined with muscular atrophy had a higher mortality risk (HR\u2009=\u20092.20, 95%CI (1.74, 2.79), p\u2009&lt;\u20090.00001).
