Fig. 1

Intergroup differences of cerebrospinal fluid (CSF) biomarkers. The gray zone includes patients classified as A + T − . Dotted lines represent cut-off values used for Aβ42, p-tau, and the p-tau/Aβ42 cut-off 0.086; the dashed line represents p-tau/Aβ42 cut-off 0.122. Bold lines represent comparisons with p-values < 0.05 at the Kruskal–Wallis
