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

Huperzine A has shown the ability to acutely improve cognitive function in certain populations, and therefore is commonly added to pre-workout supplements. However, its effects have not been studied in exercise-trained individuals.

objectiveWe hypothesized that acute consumption of huperzine A would improve cognitive function during exercise, which may be beneficial for exercise performance.

methodsFrom January to April, 2018, 15 exercise-trained individuals (11 women [height 166 ± 2 cm, weight 60.5 ± 3.0 kg] and 4 men [height 173 ± 4 cm, weight 82.0 ± 11.0 kg], BMI 23.5 ± 1.4 kg/m

resultsNo measures of cognitive function differed between placebo and huperzine A trials (all

conclusionsHuperzine A does not enhance cognitive function during exercise despite it being marketed as a cognitive enhancer. Because of its inability to enhance cognitive function, its inclusion in pre-workout supplements warrants reconsideration. Other more practical and effective strategies should be considered.
