The influence of diabetic retinopathy on the risk of dementia: A nationwide cohort study.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
We evaluated the impact of diabetic retinopathy (DMR) on dementia using clinical data from the Korean National Health Insurance Service. A nationwide, population-based retrospective cohort of 784,205 individuals over the age of 45 was analyzed. DMR diagnoses were confirmed using diagnostic and procedure codes. Covariate data, such as age, sex, income level, visual acuity, systemic and ophthalmic comorbidities, and behavioral factors, were collected from health screenings and claims data. Participants were followed until December 2017, and dementia cases were identified through registered diagnostic codes and medication prescriptions. The association between DMR and dementia was assessed using a multivariable-adjusted Cox proportional hazards model. Over an average follow-up of 10.9 ± 2.7 years, 53,934 patients were newly diagnosed with dementia. Those with DMR had a significantly higher risk of developing dementia (HR = 2.74; 95% CI = 2.44-3.08) compared to those without DMR. The risk was notably higher in patients younger than 65 years (HR = 4.07; 95% CI = 3.35-4.94) than in those aged 65 and older (HR = 2.71; 95% CI = 2.37-3.11). These findings suggest that DMR significantly increases the risk of dementia, particularly in younger patients.
