Effects from linear regression model examining the relationship between episodic memory performance (CVLT immediate and long-delay free recall, Visual Reproduction immediate and delay recall) and age, years of education, practice effects (see Materials and Methods), global Aβ, MPL suprathreshold tau, HC-RsC FC strength, and MPL suprathreshold tau × HC-RsC FC strength interaction. Bolded term indicates interaction effect visualized in Figure 4;
