Detect the disrupted brain structural connectivity in type 2 diabetes mellitus patients without cognitive impairment.
Article in World journal of diabetes, 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
backgroundCognitive decline in type 2 diabetes mellitus (T2DM) occurs years before the onset of clinical symptoms. Early detection of this incipient cognitive decline stage, which is T2DM without mild cognitive impairment, is critical for clinical intervention, yet it remains elusive and challenging to identify.
aimTo identify structural changes in the brains of T2DM patients without cognitive impairment to gain insights into the early-stage cognitive decline.
methodsUsing diffusion tensor imaging (DTI), we constructed structural brain networks in 47 T2DM patients and 47 age-/sex-matched healthy controls. Machine learning models incorporating connectivity features were developed to classify T2DM brains and predict disease duration.
resultsT2DM patients exhibited reduced global/local efficiency and small-worldness, alongside weakened connectivity in cortical regions but enhanced subcortical-frontal connections, suggesting compensatory mechanisms. A classification model leveraging 18 connectivity features achieved 92.5% accuracy in distinguishing T2DM brains. Structural connectivity patterns further predicted disease onset with an error of ± 1.9 years.
conclusionOur findings reveal early-stage brain network reorganization in T2DM, highlighting subcortical-frontal connectivity as a compensatory biomarker. The high-accuracy models demonstrate the potential of DTI-based biomarkers for preclinical cognitive decline detection.
