Predicting mortality in adults hospitalized with multiple trauma: Can the BIG score estimate risk?
Observational study in Ulusal travma ve acil cerrahi dergisi = Turkish journal of trauma & emergency surgery : TJTES, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
backgroundThis study aimed to compare the predictive performance of the BIG score (base deficit + [2.5 × international normalized ratio (INR)] + [15 - Glasgow Coma Scale (GCS)]) for in-hospital mortality in adult patients with multiple trauma against other scoring systems, including the Glasgow Coma Scale (GCS), Revised Trauma Score (RTS), and Injury Severity Score (ISS).
methodsA retrospective single-center study was conducted, including 563 adults (aged ≥18 years) with multiple trauma who were admitted to the emergency department and hospitalized between January 2022 and December 2023. Demographic and clinical characteristics, as well as trauma scoring systems (e.g., GCS, RTS, ISS, and BIG score), were analyzed between survivors and nonsurvivors to identify factors associated with in-hospital mortality.
resultsThe BIG score, along with the RTS and ISS, was identified as an independent predictor of mortality in adults with multiple trauma (p<0.001 for all comparisons). A BIG score of 10.65 was determined as the mortality cut-off, with 67.7% sensitivity and 86.5% specificity (area under the curve: 0.847; 95% confidence interval: 0.808-0.886). The BIG score demonstrated higher positive predictive value (60.8%) and negative predictive value (89.6%) compared to the other trauma scoring systems. Estimated mortality risks for BIG scores of 15 and 20 were 50% and 80%, respectively.
conclusionThe BIG score can accurately predict in-hospital mortality in adults with multiple trauma. Additionally, the BIG score was superior to the GCS, RTS, and ISS in predicting in-hospital mortality (ClinicalTrials.gov identifier: NCT06574464).
