Figure 4. One-Year Predictors of 5-Year Global Outcomes.

Receiver operating characteristics curve for the best-fit logistic regression model of 1-year clinical predictors of 5-year overall outcome disability defined by the dichotomized Extended Glasgow Outcome Scale, with scores of 7 or 8 categorized as good outcome and 6 or below categorized as disabled. The best model by Akaike information criterion contained the diagnoses of traumatic brain injury, neurobehavioral symptom severity (a 29-domain measure of neurological, cognitive, and mental health function), performance on the 7.5-m (25-ft) walk (a measure of motor strength, balance, and coordination), performance on the Wechsler Test of Adult Reading (a measure of preinjury intelligence), and performance on the Controlled Oral Word Association test (a measure of verbal fluency). AUC indicates area under the curve; dashed line, line of unity.
