1 · What the graph read from it

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.

2 · The registry

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

backgroundBlood-brain barrier (BBB) disruption is a recognized contributor to neurodegenerative diseases. However, its specific role in cognitive decline in diabetes has not been sufficiently explored.

aimsThis study aimed to evaluate the association between BBB integrity and cognitive function and to investigate the discriminative ability of BBB-related biomarkers for cognitive impairment in individuals with type 2 diabetes mellitus (T2DM).

methodsIn this case-control study, participants were recruited from the Second Affiliated Hospital of Nanchang University. All subjects underwent dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). We compared quantitative brain imaging (Ktrans and Ve) and serum platelet-derived growth factor receptor β (PDGFRβ) between diabetic individuals with and without cognitive impairment. The relationships between these biomarkers and cognitive performance were assessed using linear regression analyses. The discriminative capacity of each biomarker for distinguishing groups was evaluated using receiver operating characteristic (ROC) curve analysis.

resultsT2DM individuals with cognitive impairment exhibited significantly elevated Ktrans and Ve levels compared to those without, which correlated inversely with MoCA scores in key brain regions. Serum PDGFRβ was also independently associated with impaired cognition. Every biomarker individually demonstrated high discriminative power for evaluating cognitive status, with AUC values of 0.908 (95% CI: 0.842 to 0.973) for Ktrans, 0.923 (95% CI: 0.86 to 0.986) for Ve, and 0.839 (95% CI: 0.751 to 0.928) for PDGFRβ.

conclusionsOur results confirm the critical role of BBB dysfunction in diabetic cognitive impairment. The biomarkers serum PDGFRβ, Ktrans, and Ve showed potential associations with this condition, suggesting their clinical value for future clinical application in risk stratification and therapeutic monitoring in T2DM population.
