SCAT3 Day 8 d = –.60. Comparisons are all scaled such that negative values reflect worse performance in the mTBI group. Values are bolded where p< .05 after adjustment for multiple comparisons. SCAT3 = Sport Concussion Assessment Tool—3; SRT = Simple reaction time; CDS = code substitution-learning; PRT = procedural reaction time; MTH = mathematical processing; M2S = matching to sample; CSD = code substitution-delayed; SR2 = simple reaction time 2; GNG = go no-go; SP = spatial processing; CDR = code substitution-recall; MS = memory search; SR2 = simple reaction time trial 2; VERM = verbal memory composite; VISM = visual memory composite; VMS = visual motor speed composite; RT = reaction time composite.
