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

This study investigated the correlations between phenolic compounds and antioxidant capacities of Korean red pine (Pinus densiflora Sieb. et Zucc.) bark (RPB) fractions after in vitro gastrointestinal digestion. RPB extracts were prepared using 70% (v/v) aqueous ethanol and further fractionated with n-hexane, ethyl acetate, and water. Their antioxidant capacities were evaluated using three assays. Phenolic compounds were quantified using a liquid chromatography system to assess their stability. The antioxidant capacities of RPB extract and its fractions were significantly influenced by the digestive process. Gastric digestion increased the contents of procyanidin B1 and catechin, whereas intestinal digestion degraded most of the phenolic compounds except protocatechuic acid. Principal component analysis revealed that taxifolin had the greatest impact on data variability, indicating that this polyphenol plays an important role in the antioxidant capacity of RPB. This study provides insights into the stability and bioaccessibility of phenolic compounds in RPB under simulated gastrointestinal conditions, supporting its potential use as a source of natural antioxidants in dietary supplements.
