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.
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
This study investigated the sensory characteristics and non-volatile chemical composition of different grades of brandy using sensory descriptive analysis and widely targeted metabolomics. Significant improvements in sensory attributes, particularly oral sensation-related qualities such as smoothness, sweetness, burn, and astringency, were observed with increasing grade. A total of 682 non-volatile metabolites, dominated by phenolic compounds (44.58%) and lipids (11.88%), were identified. Grade-dependent variations in metabolite composition were revealed, with 164 compounds identified as grade-specific biomarkers. Of these, 112 metabolites were linked to taste perception, including some phenols contributing to bitterness, some saccharides and phenolic esters contributing to sweetness. This study provides a comprehensive chemical profile of brandy's sensory quality and highlights the grade difference in shaping its flavor.
