Obesity significantly elevates thromboembolism risk in severe trauma, yet essential resuscitation with TXA and erythrocytes remains safe.

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
purposeGiven obesity's rising prevalence and its established role as an independent thromboembolic risk factor, potentially inducing a procoagulant state post-trauma, this study aimed to pinpoint key obesity-related factors influencing thromboembolic occurrences in this vulnerable patient group to guide interventions.
methodsThis retrospective study analyzed a consecutive cohort of 1547 trauma patients age ≥ 18 years with an Injury-Severity-Score (ISS) ≥ 9 admitted to our level I trauma center between 01/2018 and 12/2024. Patients' data were extracted from electronic medical records. Exclusions included pregnancy, malignant/neurodegenerative disease, prior thromboembolism, and inconclusive documentation. Risk factors and influencing factors regarding obesity to suffer post-traumatic thromboembolism were evaluated.
resultsOlder age, higher Body Mass Index (BMI), and greater Injury Severity Score (ISS) (p < 0.05 for all) were identified as significant independent predictors, with BMI revealing the strongest effect (OR 1.077, p = 0.001). In the obese cohort (BMI ≥ 30), administration rates of tranexamic acid (TXA) and erythrocytes did not significantly differ between the TE and non-TE-groups (p > 0.05). Hemoglobin levels were significantly lower in the TE group at 0, 24 and 48 h post trauma (p < 0.05), while International Normalized Ratio (INR) and Partial Thromboplastin Time (aPTT) did not significantly differ.
conclusionOlder patient age, higher BMI, and ISS are independent predictors of post-traumatic thromboembolism. Crucially, the administration of TXA and erythrocyte concentrates, essential for acute hemorrhage control, was not associated with an increased thromboembolic risk in the obese cohort. These findings support aggressive hemostatic resuscitation in high-risk obese patients.
