Xenon isotopes reveal a geomagnetic prelude to Earth's oxygenation.
Article in National science review, 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
Ancient xenon isotopes reveal that a temporary weakening of Earth's magnetic field enhanced hydrogen escape to prime the atmosphere for oxygenation, before its recovery locked in the Great Oxidation Event. More than simple shields, magnetic fields may act as an active filter for atmospheric evolution, with consequences for planetary habitability and the divergent histories of Earth and Mars.
