Conditional information

How this model should be used:
The EMTRAS accurately predicts mortality. The determination of the EMTRAS will inform caregivers of the seriousness of patients with trauma at an early stage. Despite the fact that it only uses four items that can be determined early, it compared favorably with other (more complex) scores.

Model performance:
The EMTRAS demonstrated very good discrimination upon validation, with AUROCs of 0.94 (0.93-0.96) and 0.92 (0.90-0.94) for external validation cohorts consisting of 3,001 and 1,417 patients, respectively. In the orginal publication by Raum et al,  an AUROC of 0.83 (0.79-0.87) was found in the validation cohort consisting of 3314 patients.
