Observation of thermally stable polar metallic state in perovskite nitride CeWN
Article in Science advances, 2026. 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
Polar metals offer substantial potential for exotic quantum phenomena and multifunctional applications. However, the existence of a polar metal is fundamentally challenging owing to the screening of dipole-dipole interactions by conducting electrons. Specifically, a high-temperature-stabilized polar metal remains to be discovered. In this study, we report a thermally stable polar-metal state in perovskite cerium tungsten nitride. Synchrotron x-ray diffraction and electron microscopy reveal a polar
