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

Forces that animals can exert is of great interest in biology. Regarding the elephant trunk, the maximum mass that an elephant can lift with its trunk is known, but the pinching force of the trunk tip is unknown. We here present an original system to measure this force for an organ much coveted in soft robotics for example. It consists of:•A wooden box protecting the elephants and the measuring system with no protruding parts except the sensor. This box has an opening at the back to fill it with apples and a trap door at the front to release the apples.•Two load cells protruding from the box connected to an electronic system controlled by an Arduino card that records and sends the pinch force via Wi-Fi to a laptop while releasing a reward apple.•Depending on the threshold chosen, the elephant must pinch harder than the previous time to release the next apple. The repetition of this action allows us to approach the maximum force it can achieve.The system, tested on elephants at the Beauval Zooparc (France), has demonstrated that it is effective in measuring the pinching force of the tip of the trunk.
