Discovery of a multicomponent alloy forged by the Hiroshima atomic blast.
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
High-energy nuclear detonations generate extreme, transient physicochemical environments capable of producing previously unknown materials. We report the discovery of a previously unknown multicomponent alloy preserved within a hiroshimaite spherule recovered from beach sands of Hiroshima Bay, formed during the 6 August 1945 atomic airburst. The micrometer-sized metallic grain occurs within a quenched glassy matrix. Electron microprobe analyses reveal a homogeneous, Si-rich multielement composition (Fe-Cr-Ni-Mn-Mo-Si-Al). Single-crystal x-ray diffraction shows that the phase crystallizes in space group
