Figure 2. CSF Synaptic Protein Levels Statistically Moderate the Relationship Between CSF AB_42/40 and ptau₁₈₁.

Raw values plotted. All interactions were modeled continuously. Synaptic protein levels were split into sample-based tertiles for illustration purposes. Aβ = β-amyloid; GAP-43 = growth associated protein-43; ptau181 = tau phosphorylated at amino acid 181; SNAP-25 = synaptosome associated protein-25.
