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

Tropical rainforests, particularly the Amazon, function as the Earth's lungs yet absorb mercury (Hg) emitted worldwide. By introducing climate-driven variations in foliar functional traits into a global model of forest Hg uptake, we uncovered an inter-continental spatial decoupling between Hg sources and sinks. Unexpectedly, the minimally industrialized rainforests of South America and Africa exhibit the world's highest atmospheric Hg accumulation rates and greatest biomass, thus disproportionately sequestering Hg released from industrialized regions. This imbalance arises from climate-specific leaf traits that enhance Hg fixation towards lower latitudes. The model constrains global forest Hg uptake to 1155 ± 422 Mg yr
