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

Dietary supplements are products that are widely used for instance as energisers or to lose weight. There have been cases reported where undeclared ingredients present in such supplements have caused adverse effects on the health of the user. As there are many different products to choose from, it seems impossible to predict which might contain harmful components and to ban them from the market. Nonetheless, the use of dietary supplements and the experiences of users are shared in online discussions. We describe the development of a search engine to retrieve products associated with certain effects. Upon application we were able to retrieve a list of dietary supplements that are repeatedly associated with excessive effects by users on public fora. The top of the list contains supplements that have previously been banned because they contained undeclared harmful components. The use of the search engine as described here is a powerful method for making a risk-based selection of dietary supplements which can then be analysed for the presence of illegal or other unwanted components.
