1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundCardiometabolic diseases cover a spectrum of interrelated conditions linked to metabolic dysfunctions and/or cardiovascular disorders, including systemic arterial hypertension, diabetes mellitus, dyslipidemia, and obesity. Cocoa is a rich source of dietary polyphenols and has been associated with cardiovascular health benefits. However, beneficial effects of cocoa consumption and appropriate quantities in decreasing cardiometabolic risk factors have yet to be established. Therefore, we will conduct a systematic review and meta-analysis to examine the effects of cocoa consumption on cardiometabolic risk markers (total cholesterol, HDL, LDL, triglycerides, blood glucose, glycated hemoglobin, waist circumference, abdominal circumference, body mass index, systolic blood pressure and diastolic blood pressure) in adults with or without established cardiovascular risk factors.

methodsOur review will include all randomized controlled trials published in English, Portuguese and Spanish with no date of publication restrictions evaluating the effects of cocoa consumption on cardiometabolic risk markers selected from the databases MEDLINE (PubMed), LILACS, Cochrane, EMBASE, Web of Science and SciELO, and gray literature. Eligible studies must involve adults (age ≥18y), and the consumption of cocoa or dark chocolate (≥ 70% cocoa), include a control group and evaluate blood pressure, anthropometric measurements, and lipid or glycemic profiles. We will use risk-of-bias 2 (RoB2) tool to assess the risk of bias and the GRADE system to assess the strength of evidence. Statistical analyses will be performed using RStudio for Windows and R package meta. DISCUSSION: This meta-analysis will summarize existing evidence on the effects of cocoa consumption on cardiometabolic health in adults. Better understanding the effects of cocoa consumption on anthropometric measurements, blood pressure, and lipid and glycemic profiles can provide valuable insights for health professionals to improve dietary recommendations regarding appropriate quantities.
