High Serum Aβ and Vascular Risk Factors in First-Degree Relatives of Alzheimer’s Disease Patients

Table 3 Predictors of Aβ_1–40 levels among the ADAPT subpopulation

Predictors^a	β	[95% Cl]	P-value
Age (1-year increase)	2.41	[0.57 to 4.26]	0.011
Creatinine (mg/dL)	81.52	[47.29 to 115.75]	<0.001
Antihypertensive use (yes)	176.43	[1.36 to 351.50]	0.048
SBP (mmHg)	0.75	[−0.04 to 1.54]	0.063
Antihypertensive use × SPP	−1.28	[−2.57 to 0.014]	0.052

^aAnalyses were performed using multivariate regression modeling, in which age, creatinine, antihypertensive use, SBP, and the interactive term were in the same linear model.
