Resuscitative endovascular balloon occlusion of the aorta in abdominal trauma: zone-specific outcomes and predictors of mortality.
Review in International journal of emergency medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundResuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) is increasingly utilized for hemorrhage control in trauma; however, zone-specific outcomes in abdominal trauma remain inadequately characterized.
methodsWe retrospectively analyzed 404 patients with abdominal trauma who underwent REBOA between 2019 and 2022. Patients were stratified by aortic occlusion zone (zones 1, 2, or 3), and their demographic characteristics, injury patterns, resuscitation requirements, and clinical outcomes were compared.
resultsThe cohort was predominantly male (83.8%), with a median age of 35.0 years. The distribution of the zones was as follows: Zone 1 (33.7%); Zone 2 (4.7%); and Zone 3 (61.6%). Patients in Zone 1 presented with more severe hemodynamic compromise (median SBP 77.0 mmHg vs. 107.0 mmHg in Zone 2 and 103.0 mmHg in Zone 3, P < 0.001) and lower GCS scores (median 6.0 vs. 15.0 in both Zones 2 and 3, P < 0.001). Mortality was significantly higher in Zone 1 (73.6%) than in Zones 2 (27.8%) and 3 (37.7%) (P < 0.001). Multivariate analysis identified GCS score (OR 0.80 per point increase, 95% CI 0.73–0.87, P < 0.001) and Zone 3 placement (OR 0.20 vs. Zone 1, 95% CI 0.08–0.47, P < 0.001) as independent predictors of survival. Overall mortality decreased from 58% in 2019 to 36% in 2022, despite the increased utilization of REBOA.
conclusionREBOA zone placement and neurological status are powerful independent predictors of mortality in patients with abdominal trauma. These findings support a zone-specific approach to REBOA deployment in patients with abdominal trauma.
