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

Rainy weather hinders normal sunlight withering of oolong tea, which prevents the development of its high-quality characteristics. This study used representative oolong tea varieties ("Shuixian," "Ruixiang," and "Chunlan") and applied multi-wavelength LED combination light, with control group for sensory and metabolomics comparison experiments. Sensory omics results showed that LED light-withered oolong tea has a more mellow taste, with deeper orange-yellow and orange-red hues. Widely targeted metabolomics analysis revealed that LED light withering affected the taste of oolong tea by promoting transformation of key bitter-related metabolites, including flavonoids (Kaempferol-3-O-rutinoside, Epigallocatechin, Kaempferol, Robinin), alkaloids, bitter amino acids, and oligopeptides. These changes were accompanied by varying levels of umami and sweetness, resulting in more mellow taste. This research clarifies the relationship between metabolite changes and flavour enhancement following LED light withering, providing systematic theoretical foundation for the controlled light-withering of oolong tea under rainy conditions and its quality improvement.
