Sumario:INTRODUCTION: Dyslipidaemia is a critical factor in the development of atherosclerotic cardiovascular disease. Concerning dyslipidaemia regulation, we advocate for lifestyle interventions such as diet to complement drug treatment. Numerous studies have confirmed that oat β-glucan, a critical component of oats, can help lower cholesterol. However, there is no conclusive evidence for the efficacy of oats and their products in the treatment of dyslipidaemia. As a result, we have developed this protocol to serve as a guide for future research on oat intervention for dyslipidaemias. METHODS AND ANALYSIS: We will conduct a search of eight databases or websites (PubMed, Web of Science, Cochrane Library, EMBASE, CNKI, SinoMed, VIP and Wanfang) to identify studies on oats’ ability to regulate blood lipid levels. Two authors will screen articles independently, extract data based on inclusion and exclusion criteria, and assess the quality and bias of included studies. To assess and quantify heterogeneity, Q and I(2) statistics will be used. If there is significant heterogeneity between studies, the source of the heterogeneity will be investigated using subgroup analysis and sensitivity analysis. We will analyse potential publication bias using the Begg funnel plot and Egger’s weighted regression statistics. To assess the quality of evidence for the primary outcomes, the Grades of Recommendations, Assessment, Development and Evaluation method will be used. ETHICS AND DISSEMINATION: This study is based on the existing literature and data in the databases. It is not subject to ethical review. The findings, on the other hand, will be published in a peer-reviewed journal. These findings may aid in the management of dyslipidaemia on a daily basis. PROSPERO REGISTRATION NUMBER: CRD42021226751.
