Influence of multiple trauma on the effect of transfusion strategies in patients with traumatic brain injury: a sub-study of the HEMOTION trial.

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
purposeIn moderate-to-severe traumatic brain injury (TBI), anemia may exacerbate secondary cerebral injury, and patients with multiple trauma may be especially vulnerable to cerebral hypoxia. We conducted a secondary analysis of the HEMOTION trial (liberal transfusion strategy > 10 g/dL vs. restrictive > 7 g/dL), to assess whether multiple trauma modifies the effect of transfusion strategy after moderate-to-severe TBI.
methodsWe included all HEMOTION trial participants (n = 742) and defined multiple trauma using three definitions: (1) extracranial injury with Injury Severity Score (ISS) > 15; (2) extracranial injury requiring emergency extracranial surgery; (3) spinal injury with neurological deficit. The primary outcome was the 6-month Glasgow Outcome Scale Extended (GOS-E). We tested interactions between transfusion strategy and multiple trauma status using sliding dichotomy and hierarchical Poisson regression, with sensitivity analyses using classical dichotomy (GOS-E ≤ 4) and proportional odds models. Secondary outcomes included mortality, quality of life (EQ-5D-5L, QOLIBRI), functional independence (FIM), and depression (PHQ-9).
resultsWe found no interaction between multiple trauma status and transfusion strategies on the 6-month GOS-E across all three definitions. The adjusted relative risk (RR) of an unfavourable outcome with the liberal strategy was 0.87 (95% CI 0.71-1.07) for patients with ISS > 15, 0.79 (0.59-1.05) for emergency extracranial surgery, and 0.99 (0.42-2.33) for spinal cord injury. Sensitivity analyses suggested a potential interaction for patients undergoing emergency extracranial surgery (p-interaction = 0.02 for proportional odds analysis; 0.05 for classical dichotomy). A liberal strategy was associated with better FIM, EQ-5D-5L, and Qolibri scores for definitions 1 and 2, but not 3, with no consistent interaction. Mortality and PHQ-9 did not differ.
conclusionMultiple trauma status was not associated with the effect of liberal vs. restrictive transfusion strategies on the GOS-E. Patients requiring emergency extracranial surgery may warrant further investigation.
