A simplified Sequential Organ Failure Assessment score is associated with 30-day trauma mortality: A novel tool for a low-resource practice setting.
Observational study in The journal of trauma and acute care surgery, 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
backgroundThe Sequential Organ Failure Assessment (SOFA) scoring system has been validated across a range of critically-ill populations, including trauma patients, and is positively associated with risk of mortality. SOFA relies on measurement of creatinine, bilirubin, and platelets, which are laboratory values that may not be readily available in resource-limited practice settings. The present study describes a three-variable simplified Sequential Organ Failure Assessment (sSOFA) score that can be measured at bedside without the need for serum biomarkers.
methodsThe present study is a secondary analysis of the Epidemiology and Outcomes of Prolonged Trauma Care (EpiC) study, a prospective, multisite, observational cohort study enrolling patients presenting to health care facilities in the Western Cape of South Africa following major trauma. Individuals enrolled in EpiC who had one or more complete SOFA scores within the first 7 days of hospital admission were included. Simplified SOFA, which was calculated using only Glasgow Coma Scale, mean arterial pressure, and oxygen saturation, was compared with SOFA with respect to predicting mortality at 30 days.
resultsThe present study included 1,727 patients, of whom 339 (20%) experienced the endpoint of mortality within 30 days. For both SOFA and sSOFA, a higher maximum score within the first 7 days of hospitalization was associated with an increased risk of mortality, ranging from approximately 1% for a score of 0 or 1 to approximately 80% or above for a score of 12 or greater. The area under the receiver operating characteristic curves for SOFA and sSOFA were similar (0.869 vs. 0.861, p = 0.06).
conclusionA three-variable SOFA-derived scoring system that can be easily measured at bedside performs comparably to the traditional six-variable SOFA score that relies on the availability of serum biomarkers. This scoring system has potential applications in resource-limited practice settings, where laboratory values may not be readily available. LEVEL OF EVIDENCE: Diagnostic Tests or Criteria; Level III.
