Univariable Binary Logistic Regression of 6-Month TMT B Versus Statistically Significant Clinical, Demographic, Socioeconomic, CT, and MRI Predictors From Table 5

Outcome variable	Predictor	Predictor values	Univariable odds ratio (95% CI), p value	Multivariable odds ratio (95% CI), p value	Multivariable model significance	Cox and Snell pseudo-R2	Nagelkerke pseudo-R2
6-month TMT B>2 SDs above age-adjusted mean (N=61)	Any DTI axonal injury (≥1 ROI with FA>2.2 SDs below control-group mean)	Yes (19) No (42)	4.5 (1.3, 15.1); p=0.014*	4.5 (1.3, 15.1); p=0.014*	p=0.015*	9.5%*	13.9%*

CT, computed tomography; MRI, magnetic resonance imaging; GOS-E,Glasgow Outcome Scale-Extended; CI, confidence interval; DTI, diffusion tensor imaging; ROI, region of interest; FA, fractional anisotropy; SD, standard deviation; RPQ, Rivermead Postconcussion Questionnaire; TMT B, Trail Making Test B.
