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

Capsule endoscopes play an essential role in visualizing the gastrointestinal tract and identifying pathological lesions, but existing systems are still largely limited to passive visualization without therapeutic capability. Here, we present a proof-of-concept multifunctional capsule robot (MCR) integrating diagnostic imaging, magnetic navigation, wireless power transfer, and targeted thermotherapy. In the ex vivo environment, the MCR relies on magnetic navigation and control to position itself at the target site. This enables site-specific thermal ablation, where controlled high temperatures are applied within the tissue to achieve substantial cellular destruction. These results support the feasibility of the prototype's intended functions. Through a series of in vitro cellular experiments, the MCR further demonstrated controllable temperature regulation, achieving up to 89% cell mortality under 70
