The Active Soil Layer of Thawing Permafrost Is an Emergent Source for Organic Substances of Concern to Water Resources.
Article in Environmental science & technology letters, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The Tibetan Plateau and surrounding area are an important source of freshwater for approximately two billion people. Climate change has aggregated permafrost degradation in the Tibetan Plateau over the last few decades, mobilizing organic substances sequestrated in the permafrost. Of particular concern are the mobilized organic substances that would be considered persistent, mobile, and toxic (PMT) or very persistent and very mobile (vPvM). These PMT and vPvM substances would persist and be widespread in the downstream water distribution system, potentially threatening drinking water sources and groundwater quality. Our study evaluated and identified PMT and vPvM substances among 21 currently available literature reports that reported detected organic compounds in the active soil of permafrost. Our approach combined a standard evaluation scheme and a machine learning model. We reported that 34% of these detected compounds are PMT/vPvM substances; these compounds were of either synthetic, natural, or undefined origin. The impact that further permafrost degradation will have on releasing these PMT/vPvM substances on water resources should be prioritized.
