  1. Data show mean ± standard deviation, combined for studies 1 and 2. Cognitive score is calculated as a Z score relative to the healthy control group of each study, separately, as different cognitive tests were used (study 1: MoCA; study 2: ACE-III). For this reason, the HC group by definition has a mean ± SD of 0 ± 1. HC healthy control, MCI mild cognitive impairment, AD Alzheimer’s disease, YOE years of education
