AEROBIC EXERCISE ATTENUATES HEPATIC LIPID PEROXIDATION IN AN EXPERIMENTAL MODEL OF OBESITY-ASSOCIATED NAFLD.
Article in Arquivos de gastroenterologia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe global rise in obesity has been accompanied by an increasing prevalence of nonalcoholic fatty liver disease (NAFLD), for which effective non-pharmacological therapeutic strategies remain limited.
objectiveThis study investigated the effects of aerobic exercise on hepatic oxidative stress in an experimental model of obesity-associated NAFLD.
methodsNewly weaned Wistar rats were fed a highly palatable, obesity-inducing diet. After obesity was established, the animals were randomly assigned to either a trained group (n=12) or a sedentary group (n=12). The trained group underwent moderate-intensity treadmill running for eight weeks. Hepatic lipid peroxidation was assessed using the TBARS (thiobarbituric acid reactive substances) assay.
resultsAerobic training significantly reduced hepatic TBARS levels (P<0.0005), in an average of 1.8 nmol MDA/mg protein compared to the sedentary group. These benefits were significant regardless of weight gain maintenance.
conclusionThe findings suggest that regular physical exercise attenuates hepatic lipid peroxidation in an experimental model of obesity-associated NAFLD. The results support that physical exercise is an effective non-pharmacological strategy for modulating oxidative stress and preventing disease progression.
