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

objectiveEnergy drink consumption is increasing among the population, especially adolescents and young adults. The health effects of energy drinks are unknown. In this study, we investigate the effects of low caffeine energy drinks on endothelial functions assessed by flow-mediated dilation (FMD) of the brachial artery.

methodsThirty healthy volunteers (15 men, 15 women) aged 19 to 46 years participated in the study. Flow-mediated dilation measurements of the brachial artery were performed and recorded per protocol. The volunteers were asked to drink 355 mL of energy drink containing 53.25 mg of caffeine after baseline measurements, and all measurements were repeated 60 minutes later. Baseline and post-energy drink values were compared.

resultsSystolic blood pressure (p=0.592), diastolic blood pressure (p=0.714), and heart rate values (p=0.056) were similar before and after the consumption of energy drinks. Preocclusion arterial diameters (p=0.236) and blood velocities (p=0.447) did not change after energy drink consumption. FMD levels were 9.2%±4.6% and 8.1%±4.7%, respectively, before and after energy drink consumption (p=0.176). Women had a 3% increase in preocclusion arterial diameters after energy drink consumption, whereas men had a 2.6% decrease (p=0.026) Conclusion: Low caffeine energy drinks containing 53.25 mg of caffeine/355 mL can did not have any influence on blood pressure, heart rate, or endothelial functions in healthy volunteers.
