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

Despite their dominance in many terrestrial ecosystems, the impact of ectomycorrhizal fungi on organic matter decomposition is notably variable across different ecological settings. Here we outline how the influence of ectomycorrhizal fungi on decomposition of belowground organic matter pools depends, not only on the traits of the ectomycorrhizal fungi, but also on the relative dominance of other interacting fungal guilds, in a manner that is predictable across wide gradients in soil fertility. Specifically, we propose that the dominant effect of ectomycorrhizal fungi shifts from 'priming' of saprotrophs in the most fertile soils, to inhibition of saprotrophs when conditions become nitrogen-limited, and to active 'mining' of organic matter when nutrient availability is severely constrained. Thus, ectomycorrhizal fungi retard decomposition of organic matter at intermediate soil fertility but accelerate decomposition both in the most fertile and the least fertile soils. These ideas may be applied both on local fertility gradients and at the global biome scale, helping to reconcile inconsistent relationships between ectomycorrhizal fungi and soil organic matter dynamics.
