Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Dynamic behavior simulation of metal particles in gas-insulated metal-enclosed transmission lines (GIL) is crucial for predicting their migration process and distribution pattern. However, existing two-dimensional (2D) simulations of particle motion characteristics fail to accurately reflect real-world particle behavior due to the limit of spatial dimensionality. To address these issues, this study develops a three-dimensional (3D) simulation model comprising an electrostatic field analysis module and a particle tracking module, grounded in dynamic contact theory and utilizing random reflection angle. Our simulation systematically investigates the motion characteristics of spherical metal particles between electrodes and around basin-type insulators, as well as the influence of key parameters. The simulation results demonstrate that an increase in reflection angle, which determines the coupling effect of radial and axial components of particle velocity, leads to the significant expansion of radial distribution range and maximum axial displacement. Besides, particles, whether far from or near the concave surface of basin-type insulator, repeatedly collide between the high-voltage (HV) conductor and the shell upon being lifted, followed by migration toward the convex side of insulator; particles near the convex surface exhibit surface-climbing behavior along the profile of insulator. Furthermore, particle vitality has a positive correlation with applied voltage but an inverse relationship with particle size; collision frequency is predominantly influenced by applied voltage and material properties, along with little dependence on particle size. These findings can provide a robust theoretical foundation for predicting metal particle behavior in GIL systems.
