Oral anticoagulant reversal and mortality in trauma patients: a multicentre propensity score-matched cohort study.

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
Background: Oral anticoagulant (OAC) therapy increases bleeding risk but its impact on trauma outcomes and the benefit of reversal remains uncertain. This study aimed to evaluate 1/the effect of preinjury OAC therapy on trauma mortality and 2/the protective role of OAC reversal and its associated thrombotic risk. Methods: We conducted an observational study using a prospective multicenter trauma registry between January 2012 and December 2023. OAC-treated patients were matched with non-OAC-treated patients using a propensity score. Univariable and multivariable logistic regressions assessed associations between OAC therapy and day 1 and day 7 mortality. The effect of guideline-concordant OAC reversal was evaluated. Thrombotic complications were recorded. Findings: Of the 27,426 trauma patients, 3% were OAC-treated. They were older, had more comorbidities, and experienced higher mortality. After matching (n = 2196), OAC therapy remained independently associated with increased mortality (day 1: OR 2·21, 95% CI [1·41-3·43]; day 7: OR 2·06, [1·41-3·00]), with greater risk from vitamin K antagonists (VKA) than direct oral anticoagulants (DOAC). Guideline-concordant OAC reversal, achieved only in 21% of cases, independently reduced mortality at day 1 (OR 0·10, 95% CI [0·03-0·31], p < 0·01) and day 7 (OR 0·51, 95% CI [0·22-0·97], p < 0·01). No significant association was found between reversal and thrombotic complications. Interpretation: Preinjury OAC therapy substantially increased trauma mortality, particularly with VKA. Guideline-concordant reversal was associated with reduced mortality in both VKA- and DOAC-treated patients without excess thrombotic risk but remains underused. These findings emphasise the urgent need for systematic implementation of reversal strategies in OAC-treated trauma patients. Funding: The Traumabase registry is funded by several Regional Health Agencies (Agences Régionales de Santé, ARS): ARS Île-de-France, ARS Occitanie, ARS Grand Est, ARS Hauts-de-France, and ARS Auvergne-Rhône-Alpes. The registry is also funded by the French Road Safety Observatory-Road Safety Delegation Service (Observatoire National Interministériel de la Sécurité Routière-Délégation à la Sécurité Routière).
