Effects of Vitamin C Supplementation on Total Antioxidant Status, Inflammation, and Histopathological Changes in Aged Rats.
Article in Journal of biochemical and molecular toxicology, 2025. 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
This study aims to determine the effect of orally administered vitamin C (Vit C) supplementation on physiological and histopathological changes in aged rats of different genders. A total of 28 Sprague-Dawley aged male and female rats were randomly divided into four groups of seven animals per group. The study groups included the aged male control (MC), aged male with Vit C (MVC) (500 mg/kg vitamin C, orally) supplementation, female aged control (FC), and female aged with vitamin C (FVC) (500 mg/kg vitamin C, orally) supplementation groups. At the end of the study, which lasted 31 days, blood, brain, heart, liver, and kidney tissues were collected from rats under ketamine (87 mg/kg) and xylazine (13 mg/kg) anesthesia. The results indicated that although Vit C supplementation had no effect on serum Vit C levels, gender had an effect on serum Vit C levels (p < 0.05). However, Vit C supplementation and gender did not affect serum IL-6, IL-1β, TOS, and OSI levels (p > 0.05). Vit C supplementation, without the effect of gender, significantly increased TNF-α levels in MVC groups compared to MC groups (p < 0.05), while it significantly decreased them in FVC groups compared to FC groups (p < 0.05). In addition, Vit C significantly reduced histopathological alterations in brain, heart, and liver tissues associated with aging, including oxidative stress and inflammation. In conclusion, it was observed that orally administered 500 mg/kg Vit C supplementation to old rats is not an effective way to increase the Vit C pool in the body, but gender has an impact on the blood Vit C concentrations.
