Referent group is non-trauma center
Multivariable model adjusted for state, age, gender, comorbidities (valvular disease, cardiac arrhythmias, congestive heart failure, chronic pulmonary disease, obesity, coagulopathy, chronic renal failure, liver disease, diabetes, drug and alcohol abuse), ISS, AIS for each region, mechanism of injury, presence of vertebral fracture, localization of spinal injury, presence of shock, and mechanical ventilation.
OR, Odds Ratio; TSCI, traumatic spinal cord injury
Denominator is stratum-specific number of centers.
