The long horizontal line represents the median and the short horizontal lines represent the IQR. Kruskal–Wallis test with Dunn’s correction for multiple comparisons. (HC versus bvFTD P = 0.0003, HC versus PSP P = 0.0000044, AD versus bvFTD P = 0.0003, AD versus PSP P = 0.0000052, svPPA versus bvFTD P = 0.0007, svPPA versus PSP P = 0.0000057, bvFTD versus PSP P = 0.0000019; * P < 0.05, ** P < 0.001, *** P < 0.0001, **** P < 0.00001. Biologically independent samples: HC n = 15, AD n = 23, svPPA n = 17, bvFTD n = 42, PSP n = 44.
