Association of synaptic markers with core AD biomarkers in CSF. CSF VAMP-2 (A), SNAP-25 (B) and Ng (C) are plotted against core CSF AD biomarkers (Aβ42:40 ratio, p-tau, total tau) in cognitively healthy controls and AD patients. Linear regression lines are shown for each group. Shaded areas represent standard error of the regression lines
