Composite shock indices with age, GCS, and SpO2 for trauma triage outcomes: a retrospective 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
introductionThe study evaluates the effectiveness of composite indices, incorporating age, Glasgow Coma Scale (GCS), and oxygen saturation (SpO2) into shock indices, in predicting severe trauma patient outcomes in the emergency department (ED).
methodThe study was a retrospective, single-center, and cohort-based analysis of adult trauma patients (aged > 18 years) triaged as emergency severity index (ESI) levels 1 or 2 at a level 2 trauma center, conducted over 6 months. Data were collected encompassing vital signs, and composite shock indices from the shock index (SI), reverse shock index (rSI), and modified shock index (MSI) in combination with age, GCS and Spo2.
resultsA study of 437 participants revealed that composite triad-based shock indices such as rSI × SpO2 × GCS/Age, and Age SI/(SpO2 × GCS) significantly influence the differentiation of triage levels 1 and 2. The Age SI/ (SpO2 × GCS) predict in-hospital mortality, while Age MSI/ (SpO2 × GCS), predict blood transfusion necessity. The AUC for triage level discrimination was 1.00 (sensitivity 100%, specificity 100%), for in-hospital mortality 0.77 (sensitivity 69.3%, specificity 80.5%), and for blood transfusion need 0.75 (sensitivity 68.9%, specificity 70.6%).
conclusionSI, MSI, and rSI, when combined with age, GCS, and SpO2, are significant predictors of triage level discrimination, in-hospital mortality, and need for blood transfusion, suggesting that composite shock indices are more beneficial than indices alone.
