Executive Function Behavior: Mean Executive Function Behavior t Scores

Variable	Controls, Mean (SD)	SDB, Mean (SD)	Group Difference (P)	P Adjusted for CBFV
Inhibit	47.8 (9.1)	58.3 (10.8)	t₃₅ = 3.1 (.003)	.015
Shift	46.5 (7.4)	53.6 (11.6)	t_32.6 = 2.2 (.032)	.089
Emotional control	44.2 (6.9)	58.7 (11.8)	t_31.3 = 4.6 (.001)	.005
Working memory	47.2 (11.0)	62.4 (14.8)	t₃₅ = 3.5 (.001)	.007
Plan/organize	46.1 (9.1)	61.4 (13.5)	t35 = 3.9 (.001)	.002
Global executive composite	45.4 (8.2)	61.4 (13.2)	t35 = 4.3 (.001)	.001

Clinical significance on this measure >65. Significant group differences were found for all indices, the majority of which remained significant when CBFV was added as a covariate. This suggests that this variable only minimally influenced the relationship between SDB and cognitive deficit; although see “Shift,” which no longer showed a statistically significant group difference.
