Table 4.

Z-statistics for MRI white matter hyper-intensities volume and cortical thickness measures from regression models for the EF outcomes, controlling for age, education, gender, any APOE-ε4 alleles, and intracranial volume. Bolded coefficients indicate p-values <0.05

EF score	White Matter Hyper-intensities	Caudal Middle Frontal	Rostral Middle Frontal	Superior Middle Frontal	Lateral Orbito-frontal	Medial Orbito-Frontal	Pars- triangularis
ADNI-EF	−2.09	2.29	3.52	2.88	3.80	2.34	2.61
Category Fluency	−0.58	1.14	2.01	1.91	3.24	2.58	2.19
Clock Drawing	1.00	3.14	3.12	2.97	2.49	1.66	1.73
WAIS-R Digit Symbol	−2.31	1.23	2.52	2.23	2.94	1.88	1.30
Digit Span Backwards	−1.61	0.05	1.47	−0.11	1.44	1.29	0.61
Trails A^a	−0.56	1.20	1.05	0.24	1.20	0.36	0.82
Trails B^a	−1.71	2.83	3.56	2.85	3.14	1.47	3.01
Trails B–Trails A^a	−1.77	2.88	3.73	3.14	3.21	1.56	3.03

Trails scores were reversed so higher scores are better for all outcomes
