Efficacy and safety of the traditional Chinese medicine tonifying kidney (bu shen) therapy in patients with hypertension: A protocol for systematic review and meta-analysis

BACKGROUND: Hypertension becomes increasingly an alarming global health concern. There is a growing interest in treatment of traditional Chinese medicine (TCM), and tonifying kidney therapy (bushen, TKT) has been extensively used in the treatment of hypertension according to TCM theory. In this article, we outline the protocol of research projects and methods to examine comprehensively the effectiveness and safety of TKT in treating hypertensive patients. METHODS: We will collect randomized controlled trails (RCTs) that report the application of TKT for patients with hypertension from electronic databases including PubMed, EMBASE, CENTRAL, CNKI, VIP, CBM, and Wanfang database. Time of literature retrieval is set from the beginning of database construction to the end of June, 2020. Two reviewers will independently perform literature screening, data extraction, and quality assessment of included literature, and any divergences will be worked out via discussion. The primary outcomes include total efficacy rate, systolic and diastolic blood pressure change will be assessed. The secondary outcomes include clinical symptoms and adverse events will also be assessed. RevMan5.3 software will be applied to analyzing data included studies. RESULTS: This study will synthesize and analyze all collated data in order to evaluate TKT for the treatment of hypertension involves different aspects in total efficacy rate, systolic and diastolic blood pressure change, clinical symptoms, and adverse events. CONCLUSION: This study will determine the efficacy of TKT in the treatment of hypertension and recommend its clinical value based on the evaluated the effectiveness and security results.
