Development and validation of a 10-year predictive model for cardiovascular and metabolic disease risk: insights from a large-scale health examination cohort.
Article in Open heart, 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
objectiveTo develop and validate a 10-year predictive model for cardiovascular and metabolic disease (CVMD) risk using comprehensive health examination data from nearly 37 701 individuals.
methodsThis retrospective cohort study used health examination data, including demographic information, clinical measurements, laboratory tests and lifestyle factors. Potential predictors were selected based on a literature review and exploratory analysis. Machine learning techniques (including random forest and gradient boosting) were employed to develop the predictive model. The model's performance was evaluated using accuracy, sensitivity, specificity and area under the receiver operating characteristic curve (AUC). Model validation was conducted on separate test and validation sets.
resultsA total of 37 701 electric power employees were included in this study after applying rigorous inclusion and exclusion criteria. The dataset was divided into training, validation and testing sets in a 70:15:15 ratio, with no significant differences observed in baseline characteristics, ensuring robust analysis. Feature selection using the random forest classifier identified the top predictors of CVMD. Machine learning models, particularly random forest and gradient boosting, demonstrated superior predictive performance compared with traditional Cox regression methods. These results significantly outperformed traditional Cox models, which yielded an AUC of approximately 0.60. Correlation analysis revealed strong associations between key variables, such as systolic and diastolic blood pressure, low-density lipoprotein and total cholesterol, and creatinine and blood urea nitrogen, highlighting the complex interactions among CVMD risk factors.
conclusionThe developed 10-year predictive model for CVMD risk, based on health examination data, shows promising potential for early identification and targeted intervention in individuals at high risk for CVMDs. This approach could contribute to the reduction of CVMD incidence and related morbidity and mortality.
