A nutrient control on oxygenation dynamics during Earth's Great Oxidation Episode.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Earth's first rise in atmospheric oxygen occurred over a protracted period from ca. 2.43 to 2.06 billion years ago during the Great Oxidation Episode (GOE). The GOE was marked by extreme climatic instability, which likely impacted the bioavailability of the principal limiting nutrient, phosphorus. Here, we investigate phosphorus cycling across the final two glaciations of the GOE, as documented by the Transvaal Supergroup, South Africa. Utilising a phosphorus phase partitioning approach, we show that following an enhanced weathering-induced phosphorus influx that stimulated oxygenation in the aftermath of glaciation, sedimentary phosphorus recycling was controlled by feedback-driven fluctuations in sulphate availability and oceanic redox state. Biogeochemical modelling suggests that this dynamic interplay drove major instability in atmospheric oxygen levels during Earth's protracted transition to a persistently oxygenated atmosphere.
