Efficacy and safety of Jinhua Qinggan granules in the treatment of coronavirus disease 2019 (COVID-19): A systematic review and meta-analysis
Abstract
Objective: To evaluate, using meta-analysis, the efficacy and safety profile of Jinhua Qinggan granules (JHQG) in the treatment of novel coronavirus pneumonia.
Methods: We screened multiple publication databases (PubMed, Embase, The Cochrane Library, Web of Science, CNKI, WanFang, and VIP), using parameters designed to identify articles detailing randomized controlled trials relating to the treatment of novel coronavirus pneumonia with JHQG. The inclusion period for each search was the point of database inception to November 2022. Each piece of literature identified in our initial screening was independently reviewed by 2 researchers, who extracted the relevant data and evaluated the bias risk associated with the study. The data was split in 2: the control group (containing patients who had received routine treatment or placebo) and the experimental group (containing patients treated with JHQG). The meta-analysis was performed using Revman 5.4 software. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach.
Results: Four articles were selected for this study and combined included a total of 582 patients, which were subdivided into experimental (n = 347) and control (n = 235) groups. The results showed that treatment with JHQG could significantly: enhance the improvement rate of primary symptoms [relative ratio (RR) = 1.26,95% confidence interval (CI) (1.07, 1.49), P = .007] and fever [RR = 1.48, 95% CI…
