Predicting the Need for Tube Thoracostomy in Blunt Trauma Patients With Occult Pneumothorax: Observation Versus Intervention.

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
objectivesOccult pneumothorax is increasingly diagnosed in trauma patients due to widespread use of computed tomography (CT), yet its optimal management remains controversial. This study aimed to identify clinical and radiological predictors of deterioration requiring tube thoracostomy and to develop a predictive model to guide management decisions.
methodsIn this retrospective single-centre study, 166 patients with blunt trauma-associated occult pneumothorax were analyzed. Clinical and radiological variables-including subcutaneous emphysema, haemothorax volume, pneumothorax size, mechanical ventilation, and rib fractures-were evaluated for association with delayed tube thoracostomy. A weighted multivariable logistic regression model addressed class imbalance, and model performance was assessed using receiver operating characteristic (ROC) analysis.
resultsOf 166 patients, 17 (10.2%) required delayed tube thoracostomy. Subcutaneous emphysema (odds ratio [OR] 20.10, P = .001) and mechanical ventilation (OR 17.30, P = .002) were the strongest independent predictors of deterioration. Haemothorax volume also showed a significant association (OR 1.06, P = .045). Other factors, including pneumothorax size, rib fractures, age, and sex, were not predictive. The predictive model demonstrated excellent discrimination (area under the curve [AUC] = 0.97), suggesting potential for clinical risk stratification.
conclusionsPhysiological indicators such as subcutaneous emphysema and mechanical ventilation are superior to anatomical parameters in predicting deterioration among patients with occult pneumothorax. Our findings support a selective management strategy and highlight the utility of predictive modelling to guide tube thoracostomy decisions. Prospective multicentre studies are warranted to validate these results.
