Amyloid PET SUVR by quartiles of nasal Aβ42. Violin plots represent the SUVR values of Aβ PET negative (blue) and Aβ PET positive (red). Vertical lines indicate the interquartile range and medians are indicated by gray horizontal line. Statistical significance was tested by two-way ANOVA, followed by post-hoc using Dunnett. Statistical significance was determined at a p-value below of 0.05, while p-values below or equal to 0.05 and 0.01 were represented by * and **, respectively. Group sizes were as follows: Q1 (n = 41), Q2 (n = 40), Q3 (n = 40), Q4 (n = 40). Aβ, amyloid beta; ANOVA, analysis of variance; PET, positron emission tomography; SUVR, standard uptake value ratio.
