Efficacy of nutrient supplements in managing malnutrition and sarcopenia in Chronic Obstructive Pulmonary Disease (COPD) patients: a protocol for systematic review and meta-analysis
Abstract
COPD patients suffering from malnutrition or sarcopenia often incur higher healthcare costs and experience adverse clinical outcomes. Despite this, the effectiveness of nutrient supplements in this population remains uncertain. Two reviewers will independently search seven databases—PubMed, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang, Chinese Biomedical Literature Database, and the Cochrane Library—for randomized controlled trials (RCTs) published before August 31, 2024. These RCTs should compare the effects of nutrient supplements against either a standard diet or placebo supplements in patients with COPD. The risk of bias in the included studies will be evaluated using the modified Jadad scale and the Cochrane Collaboration's risk of bias tool. Data synthesis will be conducted using RevMan software. Trial sequential analysis (TSA) will be applied to the primary outcomes. Additionally, subgroup and sensitivity analyses will be performed to assess the robustness of the findings. Ethical approval is not required because this study is a secondary analysis of existing data. We will disseminate the findings through peer- reviewed publications. CRD42024585694. This systematic review and meta-analysis provides a thorough assessment of the efficacy of nutrient supplements in COPD patients, covering a wide range of studies. ·The use of the modified Jadad scale and the Cochrane Collaboration's risk of bias tool ensures a robust evaluation of study…
