Table 4 Association of amyloid-β levels with incident dementia in carriers and non-carriers of apolipoprotein ε4 allele

From: Plasma amyloid-β levels, cerebral atrophy and risk of dementia: a population-based study

Plasma Aβ levels (per SD increase) Incident dementia (n = 79)
HR (95% CI)a
APOE-ε4 carriers (n = 35) APOE-ε4 non-carriers (n = 44)
1–38 1.58 (1.01–2.89) b 1.10 (0.66–1.83)
1–40 1.03 (0.58–1.83) 1.04 (0.64–1.71)
