Explainable machine learning for depression risk prediction in adults with obesity: development of an online tool.
Article in BMC medical informatics and decision making, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundObesity significantly increases the risk of depression, yet interpretable depression risk prediction tools specifically targeting obese individuals remain very limited. This study aims to develop and validate a depression risk prediction model for individuals with obesity using data from the United States National Health and Nutrition Examination Survey (NHANES).
methodsA total of 6,271 individuals with obesity from the 2005–2020 NHANES cycles were included in this study. Feature selection was conducted using the least absolute shrinkage and selection operator regression and multivariable logistic regression to identify robust predictors. To address class imbalance, the Synthetic Minority Oversampling Technique (SMOTE) was applied to the training dataset. Nine machine-learning(ML) algorithms were developed and compared. Model interpretability was evaluated using SHapley Additive exPlanations (SHAP), and an interactive online calculator was developed based on the best-performing model to support practical clinical risk estimation.
resultsAmong the nine models, the Stacking-ensemble model demonstrated the highest performance, achieving an AUC of 0.82, along with strong balanced accuracy, F1 score, and Matthews correlation coefficient. SHAP analysis revealed that sleep disturbance, poverty-income ratio (PIR), and gender were the most influential predictors of depression risk.
conclusionML models can accurately predict depression risk in individuals with obesity. The Stacking-ensemble model showed the highest predictive performance, and an associated online calculator provides clinicians with a practical tool to rapidly estimate individual risk, supporting informed clinical decision-making. CLINICAL TRIAL NUMBER: Not applicable.
