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

Wine phenolic composition is strongly influenced by tannin structure, yet how the polymerization degree of exogenous proanthocyanidins modulates wine quality during aging remains unclear. This study investigated the effects of adding grape seed proanthocyanidins (GSP) with different mean degrees of polymerization (mDP 4.63, 3.29, and 1.31) to Cabernet Sauvignon wine by analyzing phenolic compounds, tannin structure, anthocyanin components, CIELAB color parameters, and astringency over 6 months of bottle aging. Low-mDP GSP (rich in galloylated monomers) provided the biggest initial phenolic boost, while high-mDP GSP (dominated by non-galloylated units) sustained tannin enrichment throughout aging. Low-mDP GSP accelerated tannin maturation and color evolution toward aged wine characteristics, with Mv-3-Coglu identified as a key precursor for brick-red hue development. Sensory evaluation revealed that high-mDP GSP enhanced coarse and drying astringency, whereas low-mDP GSP promoted velvety mouthfeel. These findings establish that GSP polymerization degree critically determines phenolic evolution, color stability, and mouthfeel during bottle aging, providing a scientific basis for selecting structure-specific proanthocyanidins to achieve targeted wine quality outcomes.
