Vegetation browning patterns under compound soil and atmospheric dryness in northern permafrost ecosystems.
Article in Nature communications, 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
Significant changes in vegetation greenness and browning have been observed across the northern permafrost zone, with important implications for ecosystem functioning and carbon uptake. While recent research has improved our understanding of the drivers of greening, the processes behind browning - especially the low-stature shrubs and herbaceous vegetation, which is more directly exposed to soil and atmospheric moisture deficits - remain less clear. To characterize browning patterns, we integrate multiple remote sensing datasets - including normalized difference vegetation index (NDVI), solar-induced chlorophyll fluorescence (SIF), and foliar chlorophyll concentration (FCC) - with gross primary productivity (GPP) simulations from CMIP6 Earth system models (ESM). We identify significant browning trends (-0.033 to - 0.025 decade-1, from MODIS NDVI) from 2001 to 2018, affecting approximately 20 % (~600,000 km
