Figure 1. Boxplot Comparing Amyloid PET SUVR Across Different SOMI Subgroups for the Whole Population (A) and Sample Stratified According to Aβ Status (B).

Groups significantly different from each other are connected to each other with brackets (p < 0.005). Aβ = β-amyloid; SOMI = Stages of Objective Memory Impairment; SUVR = standardized uptake value ratio.
