Efecto del consumo habitual de café en la salud cardiovascular: protocolo de una revisión de revisiones sistemáticas de la literatura

Introduction: Coffee is one of the most consumed beverages worldwide and its effect on health has not been clearly established. There is a special controversy about its effects on the cardiovascular system. The objective of this work is to synthesize the evidence on the effects of habitual coffee consumption on cardiovascular health. Methods: Review of systematic reviews of the literature published in English, Spanish, French and Portuguese in biomedical databases (Medline, Embase, Cochrane, and Lilacs). The search will be supplemented with manual searching of references of the included reviews. The information will be selected and extracted separately by two researchers, and disagreements will be resolved by consensus. The included reviews will be grouped by year of publication, outcomes, design of original studies and quality. The study will apply the Assessing Methodological Quality for Systematic Reviews checklists to assess the methodological quality of the systematic reviews. The information will be synthesized in systematized formats. Discussion: The review of reviews will synthesize the evidence of the effect of coffee on cardiovascular health and estimate the dose-response relationship.
