- Abbreviations: Aβ beta-amyloid, APOE4 apolipoprotein ε4, CI confidence interval, APOE4 apolipoprotein E ε4 allele, VRS vascular risk score, BMI body mass index, GDS geriatric depression scale
- The results of multiple linear regression analyses are presented with B coefficient values, 95% CI, and P value. Global Aβ retention values were used after natural log-transformation to achieve normal distribution. Model 1 did not include any covariates and model 2 included all potential covariates, including age, sex, education, APOE4 positivity, VRS, clinical diagnosis, BMI, GDS score, annual income status, albumin, copper, calcium, iron, transferrin, and ceruloplasmin
