Fluid biomarkers and Aβ levels dependence in tissue chamber and circulation. The correlation between the level of total tau, NF-L, UCH-L1, GFAP, Aβ40 and Aβ42 in tissue chamber (a-b) and circulation (c-d) were assessed through Pearson correlation analysis. The correlation coefficient (R2) and p-value are displayed and significant correlations are graphed. * = p < 0.05, ** = p < 0.01, *** = p < 0.001, **** < p = 0.0001
