Machine learning-based prediction of atherosclerotic cardiovascular disease risk in adults with diabetes or prediabetes.
Article in BMC cardiovascular disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundDiabetes and prediabetes significantly increase the risk of atherosclerotic cardiovascular disease (ASCVD), posing a major global health challenge. Although traditional ASCVD risk factors have been extensively studied, there is limited research on applying machine learning.
methodsThis study used data from the NHANES survey spanning 2007 to 2018, including 4,211 participants diagnosed with diabetes or prediabetes. Key variables were identified through univariate and multivariate logistic regression analyses. The dataset was randomly split into training and validation sets at a 7:3 ratio. Nine machine learning models (including CART, SVM, and GBM) were developed and evaluated using AUC, Brier scores, calibration curves, and decision curve analysis. Additionally, an online risk prediction platform was created to provide real-time ASCVD risk assessments, helping clinicians with early screening and intervention.
resultsEight variables significantly associated with ASCVD risk were identified through univariate and multivariate logistic regression analyses, including age, waist circumference, poverty–income ratio, blood urea nitrogen, total cholesterol, systolic blood pressure, hypertension, and smoking status. Based on these predictors, the SVM model achieved AUC values of 0.831 in the training set and 0.859 in the validation set, demonstrating excellent discriminative ability. Calibration curves indicated good agreement between predicted and observed risks across different risk levels, while Brier scores further supported the overall predictive accuracy of the model. Decision curve analysis showed that the model provided substantial net clinical benefit. Collectively, these evaluation metrics highlight the strong predictive performance and practical utility of the SVM model.
conclusionThe SVM model effectively predicts ASCVD risk in individuals with diabetes or prediabetes, emphasizing the importance of managing modifiable risk factors such as dyslipidemia, hypertension, smoking, and abdominal obesity. This model offers an effective tool for individualized risk assessment and early prevention, and the online platform further supports clinical application by enabling early identification and intervention for high-risk populations.
