The subtype matters: unraveling the clinical impact of TBI variants among patients with isolated blunt head injury and skull fractures.

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
introductionTraumatic Brain Injury (TBI) is a major cause of morbidity and mortality worldwide, with isolated blunt TBIs presenting unique clinical challenges. Despite extensive research, limited studies have examined how specific TBI subtypes, subdural hematoma (SDH), subarachnoid hemorrhage (SAH), epidural hemorrhage (EDH), diffuse axonal injury (DAI), and contusions-affect critical outcomes such as in-hospital mortality, ICU length of stay (LOS), and ventilation duration. Understanding these associations is essential for improving patient management and resource allocation.
objectiveThis study aims to assess the impact of TBI subtype and size on clinical outcomes, including in-hospital mortality, ICU LOS, and ventilation days, in adult patients with isolated blunt TBI and skull fractures.
methodsA retrospective cohort analysis was conducted using the ACS-TQIP-PUF (2017-2022). Logistic and linear regression models analyzed TBI subtype, size, demographics, comorbidities, and injury characteristics in patients aged ≥ 15 years with isolated blunt TBI and skull fractures. Polytrauma cases were excluded.
resultsAmong 64,111 patients, SDH > 8 mm had the highest association with in-hospital mortality (OR 4.89, p <.01). Larger SDH (> 8 mm), contusions (> 2 cm), and SAH correlated with extended ICU LOS, with DAI leading to the longest ICU stays (+ 5.73 days, p <.01) and ventilation days (+ 8.40 days, p <.01).
conclusionTBI subtype and size significantly influence patient outcomes. SDH > 8 mm poses the highest mortality risk, while DAI results in prolonged ICU stays and ventilation. These findings highlight the need for targeted management strategies to optimize care for TBI patients. LEVELS OF EVIDENCE: Level III, retrospective/epidemiological.
