Nonparametric testing on the three groups (i.e., Aβ‐pos, stable Aβ‐neg, and progressive Aβ‐neg) highlighted significant differences in the AC (Kruskal‐Wallis H (2) = 6.08, p = 0.048), AT (Kruskal‐Wallis H (2) = 7.66, p = 0.02), FI (Kruskal‐Wallis H (2) = 6.24, p = 0.044), MTA (Kruskal‐Wallis H (2) = 13.1, p = 0.001), ERICA (Kruskal‐Wallis H (2) = 16.46, p < 0.001), PA (Kruskal‐Wallis H (2) = 6.73, p = 0.03) scales, with the PVH approaching significance (Kruskal‐Wallis H (2) = 5.72, p = 0.057).
