Objective To evaluate the quality of clinical randomized controlled trials(RCT) of acupuncture in the treatment of essential hypertension. Methods We searched the RCT reports about acupuncture treatment of essential hypertension in seven databases from the database establishment to December 2019, including Web of Science, PubMed, EMBASE, Cochrane Library, CNKI, Wanfang Date, and VIP. Two researchers screened out the eligible literatures according to the inclusion and exclusion criteria, and adopted Cochrane risk bias assessment tool and consort Statement and stricta standard to assess the quality of these reports. Results 87 RCT reports were included. The statistical results of Cochrane bias risk assessment tools show that the risk of bias in most literatures is high or unclear. According to the evaluation results of CONSORT statement and STRICTA standard items, only a few items have a high rate of complete report including the eligibility criteria of subjects, the place of data collection, intervention measures, statistical method analysis of outcome indicators, types of acupuncture treatment, acupuncture stimulation methods, needle retention time, number of treatment units, frequency and duration of treatment units, and the complete report rates of those items were 63.2%, 59.8%, 50.5%, 88.5%, 100%, 92%, 81.6%, 86.2% and 75.9%. The complete report rate of other items is low or even not reported. Conclusion The quality of RCT reports of acupuncture treatment is not good. In the future research, we should pay attention to the research design, strict implementation process, standardized test report, and connect with the international front, so as to facilitate the development and spread of acupuncture treatment.
