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
To address power-frequency magnetic fields and transient magnetic disturbances in power systems, a synergistic active-passive magnetic shielding system is proposed in this paper. By combination of high-performance Fe-based amorphous alloy materials with an optimized three-axis compensation coil, finite element method (FEM) simulations and experimental validation have demonstrated the superior shielding performance of these alloys. The results indicate that this material outperforms conventional materials in terms of the magnetic field decay rate and saturation magnetic flux density. Additionally, a three-axis square compensation coil was optimized by using the simulated annealing particle swarm optimization (SimuAPSO) algorithm for winding, thereby achieving active-passive cooperative shielding that effectively suppresses residual magnetic fields. Experimental results have demonstrated a shielding effectiveness of 38-50 dB in a 1200 μT composite interference field, effectively suppressing both steady-state and transient magnetic field disturbances. This design is suitable for protecting the power equipment. This research explores the potential of Fe-based amorphous alloys for electromagnetic shielding applications.
