Cognitive decline and diabetes in the clinical setting.
Article in Medicine and pharmacy reports, 2025. 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
Objective: The aim of our study was to evaluate the prevalence of cognitive decline in patients with diabetes in the clinical setting and to identify patient characteristics directly associated with this condition. Methods: In our cross-sectional study, we applied the Mini Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) to determine cognitive function in 172 diabetic patients, in the clinical setting. We included 120 patients with type 2 diabetes (T2DM), 42 cases with type 1 diabetes (T1DM) and 10 patients with confirmed secondary diabetes (SDM). The mean age of the participants was 62.4 years (±1.01, min: 26 years, Max: 87 years), with median diabetes duration of 15±11.8 years. Results: More than half (55.23%) of the subjects presented cognitive deterioration, which was diabetes type-specific (p<0.05). Mild forms affected mostly T1DM and SDM cases (31.5% and 30% vs. T2DM: 14.5%, p=0.00), whereas moderate cognitive decline was more predominant in T2DM (21.9% vs. T1DM: 7.1%, p=0.1). A higher prevalence of severe cognitive impairment was present in T1DM (14.5% vs. T2DM: 8.7%, p=0.1).The middle-aged category (40-64 years) was characterized by a more significant reduction of cognitive function in comparison with other age groups (p=0.02).No gender-related difference in the prevalence of cognitive decline was found (female: 45.83% vs male: 45.71%, p=0.98), although severe forms were significantly more suggestive for men (15.27% vs. 4.18%, p=0.04).Diabetic ketoacidosis (DKA) at admission was more frequently associated with cognitive deterioration, in comparison with hypoglycemic events (p=0.03).In T2DM, cognitive decline (p=0.006, r=-0.342) was associated with the presence of anemia.In T2DM women, treatment with calcium-channel blockers facilitated cognitive decrement (p=0.01, r=-0.339), whereas in men, therapy for distal symmetric polyneuropathy resulted in higher MMSE/MoCA test scores (p=0.00, r=0.72).In T1DM, a higher glycemic burden evidenced by increased HbA1c (p=0.03, r=-0.364) and glycemia at admission (p=0.01, r=-0.389) was suggestive to a more severe form of cognitive impairment. Distal symmetrical polyneuropathy (p=0.05, r=-0.305) and diabetic retinopathy (p=0.03, r=-0.102) was often co-occurring with cognitive decline.Cognitive deterioration was associated with insulin therapy (p=0.05, r=-0.232). Conclusion: The prevalence of cognitive decline is high in the diabetic population. Risk stratification must start at diagnosis and physicians should follow disease progression periodically, with special attention attributed to T1DM and the middle-aged population.
