Direct observation of substitutional and interstitial dopant diffusion in oxide grain boundary.
Article in Nature communications, 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
Grain boundaries (GBs) serve as fast diffusion paths for dopant atoms, and the segregated dopants can significantly alter the materials' properties. However, the exact mechanism of fast dopant diffusion along the GBs, particularly at atomic scale, is still unclear. Here we show direct observation of preferential GB diffusion of Hf dopant atoms along the Σ31 symmetric tilt GB in α-Al
