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

Environmental protection strategies often rely on aboveground biodiversity indicators for prioritising conservation efforts. However, substantial biodiversity exists belowground, and it remains unclear whether aboveground diversity hotspots are indicative of high soil biodiversity. Using geospatial layers of vascular plant, arbuscular mycorrhizal fungi, and ectomycorrhizal fungi alpha diversity, we map plant-fungal diversity associations across different scales and evaluate evidence for potential correlation drivers. Plant-fungal diversity correlations are weak at the global scale but stronger at regional scales. Plant-arbuscular mycorrhizal fungal correlations are generally negative in forest biomes and positive in grassland biomes, whereas plant-ectomycorrhizal fungal correlations are mostly positive or neutral. We find evidence that symbiosis strength, environmental covariation, and legacy effects all influence correlation patterns. Only 8.8% of arbuscular mycorrhizal and 1.5% of ectomycorrhizal fungal diversity hotspots overlap with plant hotspots, indicating that prioritising conservation based solely on aboveground diversity may fail to capture diverse belowground regions.
