APOC3 and Alzheimer disease: After adjusting for the ApoE4 genotype, esterified cholesterol levels remained significantly different between ICH-CAA and both controls (OR: 1.583 [1.119–2.239], p = 0.010) and AD (OR: 0.525 [0.365–0.754], p = 0.0005), and ApoC-III levels also remained significantly different between ICH-CAA and controls (OR: 0.414 [0.221–0.772], p = 0.006) (Supplemental Table S3).
