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: Soil microorganisms maintain ecosystem multifunctionality, yet the group-specific pathways linking microbial diversity, community assembly, and network complexity to soil multifunctionality (SMF) during natural restoration of abandoned alpine grasslands remain unclear. Methods: We examined artificial grassland (AG) and 3-, 12-, and 31-year abandoned grasslands (AB03, AB12, and AB31) in Bayinbuluk, Xinjiang, and analyzed bacterial, fungal, and protistan diversity, community assembly, and co-occurrence networks in relation to SMF. Results: SMF was significantly higher at AB12 and AB31 than at AG. Stochastic processes dominated community assembly in all three groups: homogenizing dispersal in bacteria, drift in fungi, and in protists a shift from dispersal limitation at AB03 (90%) to drift at AB12 (100%). Bacterial network complexity was lowest at AB03, fungal complexity increased at AB31, and protistan complexity was unchanged. Partial least squares path modeling (PLS-PM) revealed divergent microbial pathways: fungal diversity and bacterial and protistan network complexity were positively associated with SMF, whereas fungal network complexity and protistan diversity showed negative associations. Discussion: Microbial-SMF linkages thus reflect a strategy of diversity dependence in fungi versus network dependence in bacteria and protists, indicating that assessing alpine grassland restoration requires group-specific rather than universal microbial indicators.
