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
The advantages of high integration density, energy efficiency, and enhanced stability make the realization of perpendicular magnetic anisotropy (PMA) in single-layer films a crucial step toward the development of advanced spintronic devices. A theoretical study predicted that the magnetic easy axis of FeRh film would reorient from out-of-plane (OP) to in-plane (IP) directions during the antiferromagnetic-ferromagnetic (AF-FM) phase transition. However, few studies have observed an OP magnetic anisotropy in FeRh films. In this work, a continuous reorientation of the magnetic easy axis from OP to IP directions in FeRh film during its AF-FM phase transition is demonstrated. Additionally, the anisotropy transition temperature increases with the film thickness. According to the magnetic domain imaging, the nucleation and initial growth of the FM domains at the AF state are dominated by magnetocrystalline anisotropy, leading to an OP easy axis in the FeRh thin film. With increasing temperature, shape anisotropy progressively dominates the magnetic properties of FeRh film, shifting the magnetic easy axis from OP to IP orientations. These findings not only demonstrate a novel anisotropy transition behavior in FeRh films, but also successfully induce PMA in such thick single-layer films, providing critical experimental insights for the application of FeRh in spintronic devices.
