Figure 1. Distribution of Longitudinal β-amyloid (Aβ) Deposition Dichotomized by Excessive Daytime Sleepiness (EDS) .

Deposition of Aβ is depicted as the unadjusted difference between the second and first Pittsburgh B compound (ΔPiB) standardized uptake value ratio (SUVR) for each region according to presence of EDS. Horizontal lines indicate median; boxes, first and third quartiles; and error bars, minimum and maximum.
