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

backgroundguarana and green tea are known as compounds that may improve cognitive performance due to their high content of caffeine and other neurostimulants, such as theobromine in the case of guarana and ECGC (apigalocatechin-3-galate) in that of green tea.

methodsthis study investigates the effects of RESULTS AND DISCUSSION: the results showed that both guarana and green tea fostered significant improvements in cognitive performance. However, more people felt the effect of guarana than the effect of green tea. The study found a strong correlation between cognitive effects and guarana administration, including improvements in energy and retention of information. For green tea, a calming effect and state of well-being were the most relevant responses.

conclusionsthe findings suggest that guarana and green tea may constitute a useful strategy for improving academic performance. However, further research is needed to determine optimal doses, frequency of consumption, and potential long-term effects on cognitive function.
