(A) Receiver operating characteristic curves for models 1 and 2. (B) Model 1 including baseline characteristics that differed between good and poor 1-year cognitive outcome at the p < 0.2 level (Tables 2 and 3). (C) Model 2 including baseline characteristics after backward stepwise regression using α = 0.05. *Defined as cognitive impairment (≥1 score on ≥2 of 3 tests meeting criteria for impairment), cognitive decline (≥1 score on ≥2 of 3 tests meeting criteria for decline), or both. For the prediction models, baseline characteristics were entered as binary variables with the following reference values as follows: White race, more than a high school (HS) education, working full-time/part-time/students, income $35,000, health insurance, no depression, no developmental disability, nonassault injury, Rotterdam score <3, emergency department (ED) glucose <200 mg/dL or not done, no diabetes, Glasgow Coma Scale (GCS) score ≥14, no anxiety, and negative toxicology screen. AUC = area under the curve; mTBI = mild traumatic brain injury.
