Self-awareness index (RMBT-based)	0.55 (4.82 ± 1.23)	<0.001
Interaction Education∗BPnd	–0.58 (–5.23 ± 1.61)	0.002
Self-awareness index (RAVLT-based)	0.38 (3.30 ± 1.27)	0.01

Data are presented as standardized Beta (unstandardized beta +standard error) or ^∗odd ratios (95% confidence intervals). Analyses were adjusted for age, sex, education and depressive symptoms. Analyses between amyloid-β load, self-proxy and self-awareness indexes were based on mean cortical amyloid-β load. Self-awareness indexes; positive associations (i.e., betas) reflect heightened self-awareness (hypernosognosia) in relation with higher amyloid-β load, whereas negative scores reflect lowered self-awareness (anosognosia).
