Figure 1 – Association of slow wave activity and amyloid-β.

Figure 1 –

Before treatment (left column), there is no significant correlation between slow wave activity as measured by delta power, and (A) Aβ40, (C) Aβ42, (E) tau, or (G) total protein in CSF. After treatment (right column), there is a significant negative correlation between SWA and (B) Aβ40 and (D) Aβ42; there is no correlation with (F) Tau or (H) total protein. Linear regression lines are shown for illustrative purposes; since the data were not normally distributed, correlations were assessed with Spearman’s correlation coefficient (r=rho) and associated p values.
