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.
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
Gallium-based liquid metals, when combined with magnetic agents, emerge as intelligent materials with potential applications in soft robotics within biomedical engineering. However, concerns have arisen from the residual presence of liquid metal, raising long-term biological risks. Herein, we propose a containment method that involves the rolling of magnetic liquid-metal droplets in lyophilized powders, resulting in the formation of intact hydrogel coatings upon hydration. These hydrogel coatings adhere to the liquid-metal surface, forming a cohesive network through hydrogen bonding between carboxylic acid groups and siloxane linkages from silanol groups. This synergy of physical and chemical interactions enables hydrogel coatings with exceptional stretchability, fracture energy and interfacial bonding to liquid metals. Consequently, the hydrogel-coated containment capsule of magnetic liquid metal exhibits remarkable resilience to cyclic compression, enduring strains of ≤85%, while also withstanding impacts from heights of >14 m. Moreover, the containment capsules demonstrate large deformation capabilities, dexterous locomotion and wireless heating under the control of static and alternating magnetic fields. They showcase the capability for remote thermal ablation operations on
