Comparison of HDL sub-distribution in HC with low (Aβ–) and high (Aβ+) Aβ deposition, expressed as % or mg/dl

	Lipoprotein fractions (% of total HDL)		Lipoprotein fractions (mg/dl)
	HC Aβ–(n = 49)	HC Aβ+ (n = 21)	HC Aβ–(n = 49)	HC Aβ+ (n = 21)
HDL L	34.3±11.2	34.5±9.5	24.4±12.6	24.6±12.5
HDL I	53.9±7.4	54.0±5.5	35.5±6.9	35.6±8.6
HDL S	11.7±6.8	11.5±5.4	7.2±3.5	7.1±2.4
General linear model
	HDL Subdistribution (% of total HDL)		HDL Subdistribution (mg/dl)
	p		p
HDL L	0.72		0.91
HDL I	0.40		0.88
HDL S	0.94		0.99

ANCOVA (analyses were adjusted for sex, age, site, and APOE ɛ4-carrier status) or non-parametric Mann-Whitney U Test were used and regarded as significant when p < 0.05. For HDL S (% and mg/dl), HDL L (mg/dl) and HDL I (mg/dl) non-parametric tests were used. Values are presented as mean±S.D.
