Completed The NMA using Stata statistical software (Version 14.0, Stata Corporation, College Station, TX). Methodological quality of articles was assessed using the Cochrane Collaborative tool, and evidence quality was assessed using the Recommended Scoring, Development, and Evaluation tool. The main indexes were Spirometry, the secondary indexes were Asthma Quality of Life Questionnaire and adverse events. Meanwhile, in order to prevent data missing, we compared the previous meta-analysis to determine the final inclusion results. The retrieval time was limited from the beginning of each database construction to September 12, 2020. The retrieval strategy was strictly followed in the English databases PubMed, Embase, Cochrane Library, and Chinese databases: CNKI and Wanfang. Traditional Chinese medicine has been widely used in the treatment of asthma, but currently there has been no comprehensive evaluation on the efficacy and safety of different traditional Chinese medicine therapies, based on network meta-analysis (NMA).
