Machine learning-based risk classification of depressive symptoms among patients with hearing loss: evidence from the Health and Retirement Study (HRS).

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
Background: Depression is a common and debilitating condition among individuals with hearing loss, substantially impairing patients' quality of life. This study aimed to develop a model to classify depressive symptoms among individuals with hearing loss. Methods: Data from 2397 patients with hearing loss in the 2016-2020 Health and Retirement Study (HRS) were analyzed. Thirty-one behavioral, health, psychological, and sociodemographic indicators were assessed, and LASSO regression was used to select predictive variables. Seven machine learning algorithms-Random Forest (RF), Logistic Regression (LR), Support Vector Machine (SVM), Multilayer Perceptron (MLP), Gradient Boosting Decision Tree (GBDT), Extreme Gradient Boosting (XGBoost), and k-nearest neighbors (KNN)-were trained to identify the optimal model. SHAP analysis was employed to provide interpretable insights, and an individualized risk stratification tool was constructed. Results: After excluding participants with incomplete data, 1693 patients were included in the final analysis, of whom 510 (30.1%) had depressive symptoms. Eleven predictors were retained for model development. Among the models, XGBoost demonstrated the most balanced overall performance. In the training set, it achieved an AUROC of 0.854 (95% CI: 0.832-0.877), an accuracy of 81.1%, a sensitivity of 56.0%, a precision of 76.1%, a specificity of 92.2%, and an F1 score of 64.5%. Limitations: The model was specifically developed for patients with hearing loss, and the clinical benefit of interventions guided by the risk remains to be validated. Conclusion: In conclusion, using data from the 2016-2020 HRS database, we developed seven machine learning models to identify risk factors among patients with hearing loss. XGBoost achieved the best predictive performance and stability, while SHAP analysis provided interpretable insights into key contributors. These findings support early risk stratification and targeted prevention strategies, with potential to enhance mental health care for this vulnerable population.
