L-Arabinose Alleviates Functional Constipation in Mice by Regulating Gut Microbiota and Metabolites.
Article in Foods (Basel, Switzerland), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Functional constipation ranks among the most common disorders impacting human health, which is manifested by difficulty in defecation and a complex etiology. L-Arabinose, a pentose found naturally in fruit rinds and cereal husks, has been reported to regulate glycolipid metabolism, improve glucose homeostasis, and exhibit anti-inflammatory effects. However, the effect and precise mechanism of L-Arabinose on functional constipation remain unclear. In this study, the effect of L-Arabinose in alleviating functional constipation induced by diphenoxylate was evaluated. The model group consisted of functional constipation mice that did not receive any intervention. The positive drug group was treated with 2.0 g/kg lactulose, while the intervention group was given 0.5 g/kg, 0.75 g/kg, 1.0 g/kg, and 2.0 g/kg L-Arabinose, respectively. The data suggested that 20 days of L-Arabinose intervention could shorten the first black stool defecation time, increase fecal water content, and enhance the rate of small intestinal propulsion in mice with functional constipation induced by diphenoxylate. Additionally, L-Arabinose reversed the protein expression of functional constipation-related intestinal factors in the colon, characterized by a decrease in the expression of water channel proteins AQP3 and AQP4, as well as an increase in the expression of tight-junction proteins ZO-1, Claudin-1 and Occludin. Furthermore, L-Arabinose modulated the levels of hormones (MTL, Gas) and neurotransmitters (5-HT, VIP) related to the digestive systems of mice with constipation, resulting in elevated levels of 5-HT, MTL, and Gas and decreasing levels of VIP. Histopathological analysis also revealed that L-Arabinose intervention improved the intestinal inflammatory response. Furthermore, 16S rRNA sequencing and metabolomics of the intestinal microbiota demonstrated that L-Arabinose treatment improved both the intestinal microbiota composition and the metabolite levels. This study suggests that L-Arabinose can serve as a potential functional ingredient to promote intestinal health, enhance gastrointestinal motility and barrier function, regulate osmotic pressure, restore neurotransmitter levels, and effectively relieve functional constipation.
