The same pattern of results was obtained when analyses were limited to CN participants, with significant PP X Age X APOE interaction effects on the Picture Sequence Memory Test ( β = 0.17; p = .039) and the Cognitive Function Composite: β = 0.17; p = .042), and marginally significant PP X Age X APOE interaction effects on the List Sorting Working Memory Test ( β = 0.14; p = .080) and the Fluid Cognition Composite ( β = 0.15; p = .058).
