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

The quality of green tea is influenced by soil microbes in addition to soil conditions and the Camellia sinensis cultivar. Arbuscular mycorrhizal (AM) fungi can significantly improve soil quality and crop productivity; however, the specific AM fungal groups that affect the catechin quality index (CQI) of green tea are not yet clear. In the present study, rhizosphere soil samples, root samples, and fresh tea leaves from six different Camellia sinensis cultivars in Hunan Province, China, were collected. The taxonomic diversity and community composition of AM fungi in the rhizosphere soil and roots were investigated using high-throughput Illumina amplicon sequencing technology, and the mycorrhizal colonization rate was assessed. The two main AM fungal genera in the Camellia sinensis roots and rhizosphere were Paraglomus and Glomus. A higher catechin quality index (HCQI) is correlated with greater accumulation of Paraglomus in the roots of Camellia sinensis. The tea cultivar and the available phosphorus content in the rhizosphere soil significantly affected the mycorrhizal colonization rate and the composition of the AM fungal community within the roots. The mycorrhizal colonization rate affected the catechin composition, consequently influencing the CQI of green tea. Furthermore, fluctuations in the proportional presence of Paraglomus and Glomus within the roots of Camellia sinensis notably affected the CQI. In summary, increased mycorrhizal colonization and increased prevalence of Paraglomus substantially increase the CQI of green tea. These findings have significant implications for the application of AM fungi in the production of high-quality green tea.
