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

Ingestible capsule robots provide a minimally invasive approach to diagnosing and treating gastrointestinal diseases. However, current capsule robots cannot realize both diagnosis and treatment because of the conflict between manufacturing simplicity and functional enhancement. Here, we present a multichamber magnetic capsule robot (macabot) to achieve selective liquid sampling and drug delivery via one-time oral intake. The engineered multichamber macabot realizes selective opening of four individual chambers in specified directions triggered by a gradient magnetic field. Such functions are decoupled from its rolling locomotion driven by a rotating magnetic field. The multichamber macabot can be split into single-chamber modules to navigate narrow intestine tracts with higher pH values. The experimental results demonstrate the capabilities of the macabot for targeted delivery, sealing, active navigation, liquid sampling and release operations. Successful validation was achieved for both
