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

Climate change has intensified the frequency and severity of urban droughts, exposing urban green spaces to abrupt and extreme water shortage that disrupts plant-microbe interactions and microbial multifunctionality. Understanding how rhizosphere and phyllosphere microbial communities respond to drought and how these shifts influence urban microbial functions is crucial for developing strategies to enhance the resilience of urban ecosystems under climate change. In this study, we conducted microcosm experiments simulating four drought intensities, integrating omics technologies with soil enzyme stoichiometry to investigate the effects of drought on microbial communities associated with Zoysia japonica (Steud) and urban microbial multifunctionality. Our results demonstrate that drought intensities significantly altered the compositions of bacterial and fungal communities in both the rhizosphere and phyllosphere. Moreover, drought enhanced microbial multifunctionality by significantly affecting 21 microbial functional potentials, including carbon fixation and denitrification. Although urban microbial multifunctionality largely returned to the control level after rehydration, five functions remained altered, including phyllosphere organic nitrogen mineralization and soil polyphenol oxidase activity. Biotic factors, particularly rhizosphere bacteria and fungi, directly influenced microbial multifunctionality during drought, whereas abiotic factors, such as electrical conductivity, dissolved organic carbon, and ammonium-nitrogen (NH
