Control - control group; sAD- sporadic Alzheimer’s disease (including negative values); sAD+- sporadic Alzheimer’s disease (negative values adjusted to LOQ); sAD–sporadic Alzheimer’s disease (negative values excluded); ASD- autism spectrum disorder; fAD - familial Alzheimer’s disease; MS - multiple sclerosis. Significant P values are shown in bold typescript.
