Mahaenggamseok-tang, a herbal medicine, for lower respiratory tract infections in pediatric patients A protocol for systematic review and meta-analysis

Abstract

Background: The aim of this study is to assess the clinical evidence for or against Mahaenggamseok-tang (MHGT) as a treatment for lower respiratory tract infections (LRTIs) in pediatric patients. Method: This systematic review will include randomized clinical trials (RCTs) of MHGT, as a treatment for LRTIs, compared with other therapies such as placebo and western medicine. The search terms will be selected according to the medical subject heading. We will search the following databases for systematic reviews from 2000 to Feb 2020: 5 English databases (The Cochrane Database of Systematic reviews, MEDLINE, Excerpta Medica dataBASE, Allied and Complementary Medicine Database, and Cumulative Index to Nursing and Allied Health Literature), 1 Chinese database, 5 Korean databases (Oriental Medicine Advanced Searching Integrated System, DataBase Periodical Information Academic (DBPIA), Research Information Service System, Korean Studies Information Service System, and National Digital Science Library), and 1 Japanese database (J-Stage). All RCTs of decoctions or alternate forms of MHGT will be included. We will search for all parallel or crossover RCTs without language restrictions. The methodological quality of the RCTs will be assessed using Cochrane risk of bias. Furthermore, the studies will be limited to those performed in children under 16 years of age. Results and Conclusions: Our systematic review and meta-analysis will provide evidence for MHGT as a treatment for LRTI. The findings can help practitioners and patients recognize more effective and safer therapeutic methods. Prospero registration number: CRD42020165698
