Chemical modification and antioxidant activity of Wendan peel 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 6 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
Wendan peel polysaccharide (PP) was modified using different chemical methods. The acetylation modification of PP using acetic anhydride method resulted in a degree of substitution of 0.42 for acetylated Wendan peel polysaccharide (Ac-PP). The phosphate method was used to phosphorylate PP, and successfully obtained phosphorylated Wendan peel polysaccharide (P-PP) with a degree of substitution of 0.21. The carboxymethylation modification of PP was carried out using isopropanol-chloroacetic acid method, and the degree of substitution of carboxymethylated Wendan peel polysaccharide (CM-PP) obtained after modification was 0.77. In order to further confirm the success of the three modification methods, nuclear magnetic resonance and infrared analysis methods were used to analyze the three derivatives, and it was found that all three derivatives had characteristic absorption peaks and functional groups, indicating that the chemical modification was successful. The antioxidant activity of PP and three chemically modified products were evaluated by measuring their ability to scavenge different free radicals. The experimental results indicated that not all chemical modifications could significantly enhance the antioxidant activity of polysaccharides. In the experiment, when vitamin C (V
