Artificial intelligence models for predicting pulmonary complications in patients with chest trauma: a retrospective study.
Article in Journal of trauma and injury, 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
purposePulmonary complications, including pneumonia and respiratory failure, continue to be major contributors to morbidity and mortality in patients with chest trauma. Although several artificial intelligence (AI) models have been developed to predict trauma mortality, there remains a lack of AI-based prediction models specifically targeting pulmonary complications in chest trauma. To address this gap, we developed and validated an explainable AI model for predicting pulmonary complications.
methodsThis retrospective analysis included 1,040 patients with blunt chest trauma who were treated at a single regional trauma center between January 2019 and March 2023. Pulmonary complications were defined as pneumonia, prolonged mechanical ventilation (>48 hours), or other major thoracic complications necessitating surgical intervention. Machine learning algorithms, including extreme gradient boosting (XGBoost), random forest, adaptive boosting (AdaBoost), light gradient boosting machine (LightGBM), and a deep neural network, were trained using hyperparameter tuning and threefold cross-validation. Model performance was evaluated by sensitivity, specificity, accuracy, balanced accuracy, F1 score, and the area under the receiver operating characteristic curve (AUC). Model interpretability was assessed using Shapley Additive Explanations (SHAP) values.
resultsAmong the total cohort, 188 patients (18.1%) developed pulmonary complications. In the independent testing dataset (n=208), XGBoost achieved the highest AUC (0.856), while AdaBoost demonstrated the highest balanced accuracy (0.779). All machine learning models outperformed conventional scoring systems. SHAP analysis identified key predictors of pulmonary complications, including age, Injury Severity Score, Glasgow Coma Scale score, Abbreviated Injury Scale of the extremity or head, initial PaO2 to fraction of inspired oxygen ratio, location of the primary rib fracture, and presence of flail motion.
conclusionsThe developed AI model accurately predicts pulmonary complications in patients with chest trauma and outperforms traditional prognostic tools. The model's explainability offers actionable clinical insights, supporting early risk stratification and evidence-based decision-making in trauma care.
