The burden of blast injuries on a level i trauma center: a comparative analysis of blast versus blunt trauma.
Article in European journal of trauma and emergency surgery : official publication of the European Trauma Society, 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
purposeWe hypothesized that blast trauma results in a greater institutional resource burden than blunt trauma.
methodsThis retrospective study compared blast trauma patients (N = 321) to blunt trauma patients (N = 9,172). A Propensity Score Matching (PSM) on Age, Sex and Injury Severity Score (ISS) was executed, yielding 1,481 matched blunt controls. The primary composite endpoint was Institutional Resource Burden, defined as requiring one or more of the following high-intensity resource metrics: prolonged hospital length of stay (LOS >7 days), ICU admission, or need for urgent surgical intervention (<6 hours from admission). Secondary endpoints included in-hospital mortality, shock-trauma room triage, any surgical intervention, multiple operations (≥ 3), massive transfusion protocol (MTP) activation, requirement for mechanical ventilation, and ICU/hospital LOS.
resultsBlast patients demonstrated a higher rate of the primary composite institutional burden (78.2 vs. 51.2, OR = 3.42, 95% CI: 2.59 - 4.51, p <0.0001). Blast mechanism independently predicted shock-trauma room triage (OR = 10.60, 95% CI: 8.18 - 13.75, p <0.0001), urgent surgery (OR = 7.49, 95% CI: 5.73 - 9.80, p <0.0001), ≥3 operations (OR = 12.40, 95% CI: 8.59 - 17.90, p <0.0001), MTP activation (OR = 11.68, 95% CI: 6.48 - 21.05, p <0.0001), and ICU admission (OR = 5.54, 95% CI: 4.37 - 7.04, p <0.0001). These differences persisted across both ISS <16 and ISS ≥16 strata.
conclusionBlast trauma imposes a significantly higher institutional resource burden than blunt trauma across all injury severity strata.
