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
Background: Xinjiang apricots ( Results: In this study, a galacturonic acid-rich heteropolysaccharide (UEDAP-4) was successfully extracted and isolated from dried apricots from Xinjiang, China. The polysaccharide is primarily composed of five monosaccharides: arabinose (Ara), rhamnose (Rha), galactose (Gal), glucose (Glc), and galacturonic acid (GalA), with a molar ratio of 28.78:20.36:6.87:5.51:38.48. The main chain of UEDAP-4 is characterized by the following structure:⟶4)-α-D-GalpA-(1 ⟶ 5)-α-L-Araf-(1 ⟶ 4)-α-D-GalpA-(1 ⟶ 2)-α-L-Araf-(1 ⟶ 3)-α-L-Araf-(1 ⟶ 4)-α-D-GalpA-(1 ⟶ 2)-α-L-Rhap-(1 ⟶ 4)-α-L-Rhap-(1 ⟶ 4)-α-D-GalpA-(1⟶, with three additional branched chains. The half-maximal inhibitory concentrations (IC Conclusions: This study significantly advances our understanding of the relationship between the structural properties of polysaccharides derived from Xinjiang dried apricots and their antioxidant activity. This discovery highlights UEDAP-4 as a promising candidate for natural antioxidants, with potential applications in food preservation, pharmaceutical formulations, and functional food development.
