Association between tea consumption and prevention of coronary artery disease: A systematic review and dose-response meta-analysis.

Background: Evidence from previous studies reporting on the relationship between tea consumption and its preventive effect on coronary artery disease (CAD) has conflicting outcomes. With the accumulation of new clinical evidence, we conducted this meta-analysis to assess tea consumption and CAD risk.

Methods: We searched PubMed, EMBASE, Cochrane Library, and Medline databases for published observational studies from their inception to May 2022.
