Preparation, structure and properties of litchi pericarp polysaccharide.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
A high purity polysaccharide (UELPP-A1) was isolated from the crude polysaccharide of litchi pericarp (UELPP) by column chromatography, and acetylated polysaccharide (AC-UELPP) was obtained by acetylation modification of the crude polysaccharide of litchi pericarp. The physicochemical properties and in vitro antioxidant activity of UELPP-A1 and AC-UELPP were compared. The C/H on UELPP-A1 was assigned by Congo red test, FTIR, 1D and 2D NMR, and its structural characteristics were characterized. The results showed that the total sugar content of neutral UELPP-A1 was significantly increased to 94.15%, and its structure did not have a triple helix structure. In addition, the in vitro antioxidant activity test showed that both polysaccharides had antioxidant activity in a dose-dependent manner. The enhancement effect of AC-UELPP with the increase of concentration was the most significant (P < 0.05). Among them, the hydroxyl radical scavenging activity was stronger than its reducing ability and superoxide anion radical at the same polysaccharide concentration. Acetylation modification can improve the antioxidant activity of UELPP and has further research value for human health care.
