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

Extreme rainfall can alter thermal and hydrological dynamics of the active layer in permafrost regions, potentially accelerating thaw and climate feedbacks, yet the specific controls on soil temperature responses remain unclear. We combined four extreme rainfall indices with three analytical approaches to assess impacts at 131 Northern Hemisphere permafrost sites, and used principal component analysis to identify soil thermal responses patterns. Results show extreme rainfall cools shallow soils but warms deeper layers. Additionally, extreme rainfall cools permafrost in humid regions, disturbed land surfaces, and areas with low ground ice and soil organic matter. In contrast, precipitation warms permafrost in arid regions, shrub-dominated landscapes, and where ground ice and organic matter are high. These patterns indicate that extreme rainfall is a major driver of permafrost change and can accelerate active-layer thaw. Because response direction and magnitude depend on regional climate and ecosystem characteristics, future climate projections must explicitly include rainfall extremes.
