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

In theory, ectomycorrhizal (EM) and saprotrophic fungi compete for nitrogen (N) found in soil organic matter. However, both positive and negative effects of EM fungi on decomposition have been observed across systems, with opposing implications for soil carbon (C) storage. The conditions driving the context dependency of fungal guild interactions remain poorly understood, which has limited our ability to predict the effects of EM fungi on biogeochemical cycling at regional and global spatial scales. To address this knowledge gap, we used a publicly available dataset of soil fungal communities to examine global patterns of relative EM and saprotrophic abundance and their influence on soil carbon and nutrient cycling. We demonstrate that EM fungal dominance and its effects on C and N cycling are predictable across the globe using only soil C : N stoichiometry, host tree functional group, and soil pH as predictors. We argue that because soil pH influences the availability and enzymatic catabolism of organic N, it determines the dominant N acquisition strategy of EM fungi, which in turn governs the directional effect of EM-saprotroph interactions on rates of organic matter decomposition in forests.
