Overweight Leads to an Increase in Vitamin E Absorption and Status in Mice.
Article in Molecular nutrition & food research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
scopeThis study investigates whether vitamin E (VE) deficiency in subjects with obesity could, at least partly, be due to a defect in VE intestinal absorption. METHODS AND
resultsMice follow either a high-fat (HF) or a control (CTL) diet for 12 weeks. The study evaluates their VE status, the expression of genes encoding proteins involved in lipid and fat-soluble vitamin intestinal absorption, and VE absorption using a γ-tocopherol-rich emulsion. HF mice have a weight (+23.0%) and an adiposity index (AI, +157.0) superior to CTL mice (p < 0.05). α-Tocopherol concentrations are higher in both plasma (+45.0%) and liver (+116.9%) of HF mice compared to CTL mice (p < 0.05). α-Tocopherol concentration in the adipose tissue of HF mice is higher than that of CTL mice after correction by the AI (+72.4%, p < 0.05). No difference is found in the expression of genes coding for proteins involved in intestinal lipid metabolism in fasting mice. After force-feeding, γ-tocopherol plasma concentration is higher in HF mice compared to CTL mice (+181.5% at 1.5 h after force-feeding, p < 0.05).
conclusionHF mice display higher status and more efficient absorption of VE than CTL mice. VE absorption is thus likely not impaired in the early stages of obesity.
