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

Albino cultivars are well suited for producing small-leaf yellow tea because of their unique leaf colour and taste. This study aimed to uncover the chemical basis for the fresh sweet taste and low bitterness/astringency of albino cultivars through metabolomics. We identified 20 core taste compounds, namely 13 flavonoids, 5 amino acids (AAs), and 2 catechins. Compared with the control 'Fudingdabaicha', 'Naibai' contained a higher number of umami AAs (theanine: 45.84 mg/g; glutamic acid: 10.27 mg/g) and lower catechin levels. Quantitative descriptive analysis showed that albino cultivars exhibited stronger umami and sweetness but reduced bitterness and astringency, suggesting that umami compounds can mitigate the perception of bitterness and astringency. Weighted gene co-expression network analysis indicated that AAs are associated with umami taste, whereas flavonoids, catechins, and caffeine influence bitterness and astringency. These findings support the conclusion that the combination of elevated AA levels and reduced catechin levels is the primary driver of the fresh sweet taste of albino cultivars.
