Table 2. Odds ratios of APOE4 for developing MCI and dementia, stratified by genotype of VC transporter genes.

Gene symbol	SNP ID	Genotype group	APOE4
			Odds ratio	95% CI	p value
SLC2A1	rs710218	TT	2.35	1.05–5.23	0.037 *
		TA+AA	1.3	0.62–2.75	0.49
	rs841851	AA	3.2	1.58–6.46	0.0012 *
		AG+GG	0.67	0.27–1.67	0.39
SLC23A2	rs1279683	GG	1.21	0.44–3.37	0.71
		GA+AA	2.02	1.05–3.87	0.035 *

Odds ratio of APOE4 was calculated by multivariate logistic regression analysis, adjusted for effects of baseline age, follow-up period, baseline MMSE points, and sex.

* p < 0.05.
