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
purposeAccurate trauma triage ensures timely and specialized care for potentially critically injured patients. Undertriage remains a concern, particularly for patients without obvious vital sign derangements. This study evaluates the potential of biomarkers such as lactate, base deficit (BD), and blood glucose to improve triage score accuracy in identifying patients with severe injuries (Injury Severity Score [ISS] > 15) and predicting intensive care unit (ICU) admission without a high risk of severe injury (HRSI).
methodsThis retrospective, single-center cohort study (2017-2021) included trauma patients with trauma team activation (TTA) due to mechanism of injury(MOI) and therefore only patients with moderate risk of severe injury criteria(MRSI). Exclusion criteria were any HRSI-criterion such as advanced airway management, Glasgow Coma Scale < 12, systolic blood pressure < 90 mmHg, and specific injury patterns. Biomarkers were collected upon emergency department (ED) admission. Logistic regression and receiver operating characteristic (ROC) curve analyses evaluated biomarker predictive value alone and in combination with existing triage scores.
resultsThe study population included 3371 TTAs of which we were able to include 302 in our study-group. 15% had ISS > 15. These patients had significantly higher lactate (2.38 ± 1.2 vs. 1.57 ± 0.75 mmol/L, p < 0.05), BD (-0.2 ± 5.0 vs. 1.7 ± 2.7 mmol/L, p < 0.05), and blood glucose (144.8 ± 46.0 vs. 118 ± 37.9 mg/dL, p < 0.05). Augmenting triage scores with lactate improved predictive accuracy, with the highest AUC (0.774) observed for the age-lactate model. ICU admission prediction was less robust (AUC = 0.674).
conclusionOur findings suggest that biomarkers such as lactate could strengthen trauma triage scores, but prospective, multicenter validation is essential to confirm these preliminary results.
