Z-scaled memory is reported as age, sex and education adjusted means [95% CI] which were exported from a linear mixed model including 105 participants and a total of 222 observations. Time from baseline is reported as mean (SD) in days. Abbreviations: AD = Alzheimer’s disease, CI = Confidence interval, HC = Healthy control, MCI = Mild cognitive impairment, SCD = Subjective cognitive decline.
