Fig. 1: miRNA15b is significantly lower in the Aβ-PET negative subgroup compared with the Aβ-PET positive.

*Kruskal–Wallis one-way ANOVA on ranks test; p value: 0.045 (see Table 1 for descriptive data). Plasma miR-15b concentration is reported in terms of relative quantity. PET positron emission tomography, Aβ amyloid beta, n.s. not significant, miRNA microRNA.
