Figure 5.

Adjusted odds ratios of mortality for patients, by race/ethnicity, treated at a low mortality trauma center compared to patients of the same race/ethnicity treated at a high mortality trauma center.

Co-variates used to risk-adjust were: age, gender, type of injury (blunt versus penetrating), presence of hypotension at admission (systolic blood pressure <90 mmHg), pulse rate at admission, total Glasgow Coma Scale, Injury Severity Score, presence of severe head injury [Abbreviated Injury Scale (AIS) ≥3] and need for ventilator use. The black line represents the OR for the reference group i.e. patients of the same race/ethnicity treated at high mortality trauma centers.
