Table 4. Association between CHRNA7 SNPs and VaD by APOE ε4 status.

All models were adjusted for age, sex, APOE ε4, and education year and conditional on 5-year age strata. Numbers in bold indicate significant findings (P < 0.05). The results became non-significant after correction for multiple tests. Abbreviations: VaD, vascular dementia; AOR, adjusted odds ratio; CI, confidence interval; SNP, single nucleotide polymorphism; APOE, apolipoprotein E.
