Table 5.

Z-statistics for baseline CSF measures from regression models for the EF outcomes, controlling for age, education, gender and any APOE-ε4 alleles. Bolded coefficients indicate p-values <0.05

EF score	Aβ<192	Total tau<93	P-tau<23	AD Signature
ADNI-EF	−4.47	−2.65	−3.72	−4.39
Category Fluency	−1.94	−1.14	−2.04	−2.15
Clock Drawing	−1.06	−1.00	−0.82	−0.77
WAIS-R Digit Symbol	−4.64	−2.46	−3.19	−4.51
Digit Span Backwards	−1.17	−0.24	−0.20	−0.47
Trails A^a	−3.92	−1.94	−2.98	−3.85
Trails B^a	−3.09	−0.95	−2.32	−3.05
Trails B–Trails A^a	−2.16	−0.33	−1.49	−2.11

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