Combination of Jinshuibao Capsules and Conventional Pharmaceutical Treatments for Patients with Stable Chronic Obstructive Pulmonary Disease: A Systematic Review and a Meta-Analysis
Review question / Objective: Jinshuibao capsules are derived from Cordyceps, and they have been widely used in the treatment of different diseases. They have also been utilized in the treatment of respiratory diseases, while their effects on patients with stable chronic obstructive pulmonary disease (COPD) have remained elusive. The present study aimed to compare the efficacy of Jinshuibao capsules plus conventional pharmaceutical treatments (CPT) versus CPT alone for patients with stable COPD. Information sources: It was attempted to conduct a systematic review and a meta-analysis based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. In addition, PubMed, EMBASE, Cochrane Library, Web of Science, China Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, VIP Information Resource Integration Service Platform (CQVIP), and China Biomedicine (SinoMed) databases were searched from inception until September 30, 2021. Google Scholar and the China Clinical Trial Registry were also searched for retrieving missing data. In emergency conditions, we contacted the corresponding authors of retrieved studies for collection of additional data.
