Predicting outcome after traumatic brain injury: practical prognostic models based on large cohort of international patients

To develop and validate practical prognostic models for death at 14 days and for death or severe disability six months after traumatic brain injury.

Multivariable logistic regression to select variables that were independently associated with two patient outcomes. Two models designed: "basic" model (demographic and clinical variables only) and "CT" model (basic model plus results of computed tomography). The models were subsequently developed for high and low-middle income countries separately.
