Abstract
Aims
Diabetic Retinopathy (DR), a common microvascular complication of diabetes, has been associated with an increased risk of dementia. This study aimed to develop Machine Learning (ML) models to predict DR occurrence and evaluate its potential as a prognostic biomarker for dementia.
Methods
We included 27,929 patients aged ≥ 50 years newly diagnosed with type 2 diabetes mellitus without prior dementia or eye disease. Prediction models for DR within one year were developed using three ML algorithms: extreme gradient boosting (XGBoost), random forest, and least absolute shrinkage and selection operator. The best-performing model was externally validated across eight institutions. Patients were followed for three years to assess dementia incidence. Dementia risk between ML-predicted DR and non-DR groups was compared using Kaplan-Meier and Cox regression, with results pooled via meta-analysis.
Results
XGBoost demonstrated the best performance (AUROC: 0.746), with external validation AUROCs ranging from 0.555 to 0.620. Predicted DR was significantly associated with increased all-cause dementia risk (HR: 1.32, 95% confidence interval [CI] 1.12–1.56), Alzheimer’s disease (HR: 1.30, 95% CI 1.07–1.58), and vascular dementia (HR: 1.38, 95% CI 1.12–1.69).
Conclusions
ML-predicted DR was significantly associated with future dementia, highlighting its value in early risk stratification among patients with diabetes.
期刊介绍:
Diabetes Research and Clinical Practice is an international journal for health-care providers and clinically oriented researchers that publishes high-quality original research articles and expert reviews in diabetes and related areas. The role of the journal is to provide a venue for dissemination of knowledge and discussion of topics related to diabetes clinical research and patient care. Topics of focus include translational science, genetics, immunology, nutrition, psychosocial research, epidemiology, prevention, socio-economic research, complications, new treatments, technologies and therapy.
