Methane trapping in permafrost soils: a biogeochemical dataset across Alaskan boreal-Arctic gradient.
Article in Scientific data, 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
Permafrost soils store vast amounts of organic carbon, and their thawing due to climate warming accelerates the release of carbon as methane and carbon dioxide, exacerbating global climate change. Understanding the distribution of greenhouse gases trapped in these soils and predicting their behavior upon thawing is essential for accurately modeling climate feedbacks. This study presents an integrated biogeochemical and microbial dataset from ~1.8 m deep soil cores collected across a 970 km latitudinal gradient in Alaskan permafrost regions, spanning boreal forest and Arctic tundra biomes. This dataset includes vertical profiles of trapped greenhouse gases, their stable isotope signatures, soil physicochemical properties, and the composition and abundance of key methanogenic and methanotrophic genes. These data provide critical insights into methane cycling within permafrost soils in high-latitude ecosystems and contribute to refining the parameterization of biogeochemical processes in climate models, especially in the context of accelerating permafrost thaw.
