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

Duyun Maojian is a geographical-landmark product of Guizhou, with the processing technology included on the list of intangible cultural heritage. There are a few reports on the processing features of this green tea. This study investigated differences among five grades of Duyun Maojian by integrating objective component analysis with subjective aspects, including functional and sensory evaluations. The GC-MS analysis identified 78 key differential aroma components, primarily terpenes, alkanes, and esters, that contributed to the differences. LC-MS/MS data identified 23 key differential metabolites, including flavonoids and amino acids, as the primary differential metabolites for grade discrimination. Antioxidant, anti-inflammatory, and anti-thrombotic assays demonstrated the significant potential of Duyun Maojian for vascular protection. Sensory evaluation revealed grade-dependent variations in bitterness and umami that align with trends in TPC and TFAA. This study indicated that picking timing, picking part, and processing applicability play vital roles in determining tea quality, and smell is an essential basis for grading.
