β = standardised betas reflecting per standard deviation increased polygenic risk (PGR), and per APOE e4 allele. Bold = significant p < 0.05. Models are partially adjusted for age, BMI, sex, genotyping chip, 8 genetic principal components and fully adjusted for additional smoking, APOE e4 dose and social deprivation.
