approached significancep = .09
The interactions between APOE ε4 status and the 5e −8 PRS in relation to Aβ42 only approached significance (total sample: p = .09, CDR = 0 subsample: p = .1), but similar to results for the 39-SNP PRS, stratification based on ε4 status showed an association in ε4 carriers in the total sample (β = −56.1, SE = 22.6 p = .02), and a borderline association in the CDR = 0 subsample (β = −48.3, SE = 25.1, p = .06).
