The Role of Inflammation, Oxidative Stress, Neuronal Damage, and Endothelial Dysfunction in the Neuropathology of Cognitive Complications in Diabetes: A Moderation and Mediation Analysis.
Article in Brain and behavior, 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
objectiveCognitive impairment is increasingly recognized as a complication of diabetes, yet the underlying pathology remains unclear. This study aims to investigate the roles of inflammation, oxidative stress, endothelial dysfunction, and neuronal damage in the neuropathology underlying diabetes related cognitive impairment.
methodsThis study assessed 183 participants (54 prediabetes, 71 Type 2 diabetes mellitus [T2DM], and 58 controls) for cognitive performance using the Montreal Cognitive Assessment (MoCA). Blood samples were analyzed for interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), malondialdehyde (MDA), VCAM-1/CD106, and neuron-specific enolase (NSE) using ELISA. Mediation and moderator analysis methods were used to examine the roles of these biomarkers in diabetes-related cognitive impairment.
resultsAfter adjusting for age, education, and gender, group comparisons revealed significant cognitive impairment in patients with T2DM, particularly in visuospatial functions, naming, language, and memory performance, compared to the control group. The patients with T2DM and prediabetes exhibited similar performance in cognitive functions, except for language. Significant differences in VCAM-1 and TNF-α levels were observed; however, these biomarkers did not mediate the effect of T2DM and prediabetes on cognitive functions. Nevertheless, VCAM-1 was found to moderate abstraction abilities in T2DM.
conclusionPrediabetes represents a transitional stage not only for the pathology of diabetes but also for cognitive complications. Although there were correlations between cognitive performance and various cognitive scores, IL-6, MDA, NSE, VCAM-1, and TNF-α did not play a mediator role in the neuropathology of diabetes-related cognitive impairment.
