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

introductionGastric electrical stimulation (GES) is an effective treatment for gastroparesis. However, the available devices are equipped with bulky batteries that need to be replaced regularly by surgery.

methodsOur new implantable system consists of only 6 passive components in addition to a diode and does not require a battery. Two acute porcine experiments were carried out with a robotic surgical system for placement of the prototypes. The stimulation parameters were set with an extracorporeal unit and GES was performed. The recorded electromyography (EMG) signal was subjected to a multiresolution analysis.

resultsThe robot-assisted placement of the prototypes was successful. The inductive energy transfer was confirmed to be functional and EMG analysis revealed changes in gastric electrical activity.

conclusionsFurther technological and rapid regulatory solutions are being sought in order to start a clinical trial with the next generation devices in the near future.
