Key result
Machine learning matches traditional logistic regression for predicting abnormal c-IMT in T2D.
Why the study?
Carotid intima-media thickness is a reliable cardiovascular risk factor in type 2 diabetes, but the comparative effectiveness of machine learning methods versus traditional logistic regression for predicting c-IMT was unclear.
Do machine learning methods improve the prediction of abnormal carotid intima-media thickness compared to traditional multiple logistic regression in patients with type 2 diabetes?

Do machine learning methods improve the prediction of abnormal carotid intima-media thickness compared to traditional multiple logistic regression in patients with type 2 diabetes?
Absolute Event Rate: 0.692% vs 0.692%
Machine learning models, such as random forest and XGBoost, can improve the prediction of abnormal carotid intima-media thickness in patients with type 2 diabetes compared to conventional logistic regression, potentially aiding in early cardiovascular disease risk identification.
Noninferior ML performance does not support replacing logistic regression for CIMT prediction in type 2 diabetes; leaves open need for prospective validation.
Carotid intima-media thickness (c-IMT) is a reliable risk factor for cardiovascular disease risk in type 2 diabetes (T2D) patients. The present study aimed to compare the effectiveness of different machine learning methods and traditional multiple logistic regression in predicting c-IMT using baseline features and to establish the most significant risk factors in a T2D cohort. We followed up with 924 patients with T2D for four years, with 75% of the participants used for model development. Machine learning methods, including classification and regression tree, random forest, eXtreme gradient boosting, and Naïve Bayes classifier, were used to predict c-IMT. The results showed that all machine learning methods, except for classification and regression tree, were not inferior to multiple logistic regression in predicting c-IMT in terms of higher area under receiver operation curve. The most significant risk factors for c-IMT were age, sex, creatinine, body mass index, diastolic blood pressure, and duration of diabetes, sequentially. Conclusively, machine learning methods could improve the prediction of c-IMT in T2D patients compared to conventional logistic regression models. This could have crucial implications for the early identification and management of cardiovascular disease in T2D patients.

Wu et al. (2023) conducted an observational in Type 2 Diabetes (n=924). Machine learning methods (Random Forest, XGBoost, Naïve Bayes) vs. Multiple logistic regression was evaluated on Area under the receiver operating characteristic curve (AUC) for predicting abnormal carotid intima-media thickness. Machine learning methods, including random forest and Naïve Bayes, achieved an AUC of 0.692, demonstrating noninferiority to traditional multiple logistic regression for predicting abnormal carotid intima-media thickness in patients with type 2 diabetes.
