  1. Results within the total sample are adjusted for sex, age, principal components, and diagnostic status. Results within the diagnostic groups are adjusted for sex, age, and principal components. Significant p values are shown in bold
  2. *Values presented in the “non-APOE PRS column” are adjusted for ε4-carriership instead of excluding APOE
