Stable magnetic soft structures.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Magnetic soft structures are highly versatile in unstructured environments, making them attractive for minimally invasive medical devices. However, this versatility also renders them susceptible to unintended deformations under fluctuating magnetic fields. The challenge is further compounded by medical imaging limitations that hinder accurate estimation of device pose and shape and by anatomical boundaries that enforce misalignment with the field. Collectively, these factors can cause uncontrolled shape change and functional failure. Here, we focus on slender magnetic soft structures to investigate their stability under misaligned fields. Our anisotropic design, achieved through flexural joints, yields ~52-fold higher bending stiffness in the preferred direction and ~18-fold higher torsional stiffness than isotropic beams. This structure serves as a building block for stable spiral tentacles, helices, planar sheets, expandable devices, cubes, and three-dimensional tessellation. We validate robustness through wormlike self-propulsion, guidewire navigation with 30-fold lower insertion force, and capsule peristaltic locomotion, advancing safer, more controllable devices.
