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

Introduction: Biological nitrogen fixation is a key microbial process sustaining nutrient cycling and plant productivity in nitrogen-limited alpine meadows. However, how alpine meadow degradation reshapes diazotrophic community composition and assembly across different plant species, and how these changes relate to aboveground biomass, remain poorly understood. Methods: We used the nifH gene as a molecular marker to investigate diazotrophic communities in rhizosphere and bulk soils associated with the legume Results: Meadow degradation markedly reduced diazotroph Discussion: These findings indicate that alpine meadow degradation reorganizes diazotrophic diversity, community assembly, and potential source contributions between legume and sedge soils. Legume soils may therefore represent an important diazotroph reservoir for sedge-associated soils during alpine meadow degradation.
