Abstract:Objective To evaluate the risk of bias and reporting quality of animal experimental studies on acupuncture for hypertension, and analyze the deficiencies in experimental design, implementation and reporting, so as to decrease the risk of bias of researches and improve the reporting quality of animal studies. Methods Databases including China national knowledge infrastructure(CNKI), Wanfang database(WANFANG), Chinese science and technology periodical database(VIP), Chinese biomedical literature database(CBM), Web of Science, PubMed, Embase, and The Cochrane Library were searched from inception to October 8, 2022. Two researchers independently screened experimental studies related to acupuncture interventions in hypertensive animals according to eligibility criteria. The SYRCLE’s tool and the ARRIVE guidelines 2.0 were used to evaluate the risk of bias and reporting quality of the included literature. Excel 2019 was used to extract data and descriptive analysis was conducted according to the results. Results A total of 79 animal experiments on acupuncture for hypertension were included, among which 16 and 21 were published in Chinese core journals and science citation index(SCI)journals respectively. The result of SYRCLE’s tool showed that 5 of the 10 items were evaluated as well, while the rest were unclear risk or high risk of bias. Of the 79 included articles, the risk of bias of 19 articles were low, while the remaining studies had some risk of bias. The results of the ARRIVE guidelines 2.0 indicated that 19 of the 38 sub-items were well reported, while the rest were poorly reported.The reporting quality of 51 articles were good and the remaining studies were inadequately reported. Conclusions At present, the risk of bias of acupuncture intervention in hypertensive animal experiments is high and the reporting quality is generally low. The inadequate description of some important entries had impact on the reproducibility of the experiments and the translation of the results.The SYRCLE’s tool and ARRIVE guidelines 2.0 are recommended to be used as reference during experimental design and reporting, thus improving the standardization and reporting quality of acupuncture for hypertensive animals.
