Cognitive and Neuropsychiatric Test Performance in the Former NFL Players and Controls

	Former NFL Players (n = 65–66)^*	Controls (n = 21)	P-value
Cognitive Function, mean (SD) T-score
NAB List Learning Delayed Recall	41.92 (13.77)	50.38 (12.64)	0.0415
Trail Making Test Part B	45.12 (15.01)	52.14 (15.45)	0.1076
Neuropsychiatric Status
CES-D, mean (SD) raw score	21.14 (13.76)	3.71 (4.15)	<0.0001
BRIEF-A BRI, mean (SD) T-score	62.62 (11.49)	47.24 (9.43)	<0.0001

Note. The control group was required to be asymptomatic and have no history of head trauma at the time of recruitment. Mixed-effect models controlling for age and body mass index compered the former NFL players and controls on each of the clinical measures.

The sample size was reduced to 66 former NFL players due to exclusion of two participants for evidence of intentional symptom exaggeration; sample size for TMT B was further reduced to 65 former NFL players due to missing data.
