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

The development of ferrite-based absorbers for high-frequency integrated electronics and fifth-generation (5G) communication systems has long been constrained by the Snoek limit, which causes a pronounced deterioration of complex permeability in the gigahertz (GHz) range. Here, we overcome this bottleneck by constructing well-dispersed and rigidly anchored CoFe phases within a W-type hexaferrite matrix through an in situ thermal-exsolution strategy, yielding coherent alloy/oxide heterostructures. The nanoscale interfaces establish strong exchange coupling and tailored local anisotropy, which stabilize the real permeability and extend natural resonance for magnetic loss across 2∼8 GHz, effectively surpassing the Snoek limit. The resulting composite achieves an absorption bandwidth of 7.7 GHz at 1.4 mm, enabled by balanced impedance matching and enhanced attenuation capability, and offers a practical route for mitigating 5G electromagnetic interference. This study provides a link between macroscopic permeability parameters and nanoscale magnetic configurations, guiding the design of high‑performance magnetic-response materials.
