We derived genome-wide PRS for AD dementia using ADGC GWAS as the discovery sample with three different P-value thresholds (PT used to select training set SNPs: 0.0001, 0.001, and 0.01) and apply them to (A) Z-score of the composite memory or global cognition score; and (B) each of the markers of vascular pathologies. Age and sex were included as covariates in the association analyses.
Each pair is shown on the x-axis and the proportion of variance explained for each phenotype (estimated via partial correlation R2) on the y-axis.
Unadjusted P-values are shown on the top of the bars if < 0.05.
An asterisk indicates Bonferroni-corrected P-value < 0.05.
