Note: Effect sizes were computed using z-scores adjusted for age, sex, and education using formulae from Shrick et al. (2011). Bolded ds have ps < 0.05. SMC = Subjective Memory Complaint.
Participants reporting a SMC had lower Logical Memory Delay scores than those without SMC when analyzing only participants with a delay interval ≥ 23min.
