Extended Data Fig. 7. Plasma pTau181 and plasma NfL concentrations per FTP-PET estimated Braak stage.
A. Plasma pTau181 was increased in Braak stage 5-6, and Braak stage 3-4 compared to Braak stage 0 (n=97). B. There was no difference in plasma NfL concentrations between the different Braak stages (n=61). ***p<0.0001
