1 · What the graph read from it

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.

2 · The registry

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

Soils and sediments store a tremendous amount of organic carbon (OC), especially in the Arctic, but its long-term degradation rate remains poorly constrained. Most work estimate terrestrial OC loss from short-term incubation experiments spanning hours to years, even though soils and sediments develop over centuries to millennia. We quantify the changes in OC reactivity and composition across a chronosequence of floodplain deposits in discontinuous permafrost along the Koyukuk River, central Alaska. We observe minimal OC loss over ca. 6000 years, in sharp contrast to the cycling of surface biomass, which decays on decadal timescales in these environments. These results demonstrate that high-latitude permafrost floodplains are efficient carbon reservoirs that trap and preserve organic matter in transient sedimentary archives. The fate of these highly efficacious OC stores depends on the future dynamics of river migration, erosion, and sediment transport-as much as on changes to plant productivity in a warmer climate.
