Comparative study of polysaccharide metabolites in purple, orange, and white
Article in Food chemistry: X, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
We employed LC-MS/MS to investigate the metabolic profiles of polysaccharide compounds in white, orange, and purple sweet potato flesh. Comparisons between Orange vs White, Purple vs Orange, and Purple vs White identified 69 polysaccharide metabolites, including 23, 36, and 44 differential metabolites, respectively, with distinct differentiation. Among the three sample groups, 14 polysaccharide compounds and 2 anthocyanins exhibited significant differences. Our further analysis indicated that anthocyanins occupy a central position in the related network diagram and are interconnected with polysaccharides. In metabolic pathways, sucrose and the anthocyanin precursor UDP-glucose were upregulated in purple sweet potatoes, along with elevated levels of pelargonidin 3-O-β-D-sambubioside and delphinidin 3,5-diglucoside. Conversely, sucrose was downregulated in purple sweet potatoes while increasing in white and orange varieties. Therefore, we hypothesize that the competition between sugars and anthocyanins for shared biosynthesis precursors is attributed to differential polysaccharide metabolites among sweet potato tubers of three colors.
