Value of the biochemical biomarkers (mean ± standard deviation) used for discrimination between AD and non-AD patients.

	Control	AD	p-value
N	33 (47.2% Male)	22 (22.7% Male)
Aβ1-40 (pg/ml)	10863.7 ± 4014.6	15413.9 ± 8628.6	5.2 × 10–3
Aβ1-42 (pg/ml)	943.4 ± 287.6	465.7 ± 137.9	<1.0 × 10–4
p-Tau (pg/ml)	51.2 ± 30.9	93.7 ± 43.2	2.9 × 10–3
Total-Tau (pg/ml)	282.3 ± 194.6	717.4 ± 507.9	3.0 × 10–4
Aβ1-42∗10/Aβ1-40	0.9 ± 0.2	0.39 ± 0.2	<1.0 × 10–4

Least squares multiple regression analysis was used to analyze the relationship between the dependent variables (biomarkers) and the independent variables (age, gender, disease). A p < 0.05 was considered statistically significant.
