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

Pukeng tea (PKT), a traditional Chinese dark tea, has been consumed for centuries, yet its volatile and microbial dynamics remain unclear. This study integrated metabolomics, chemometrics, and microbiome analysis to explore PKTs with 3-20 years of storage. HS-SPME-GC-MS identified 189 volatiles, mainly alcohols, aldehydes, and ketones. PCA and PLS-DA revealed distinct metabolite patterns, with 46 differential volatiles, such as 1-butanol and 1-penten-3-ol, characterized as potential discriminants among PKT samples. Microbiota analysis showed 11 dominant bacterial genera, shifting from Firmicutes in early storage to Actinobacteriota in later stages, while
