CSF SNAP-25 and Ng by amyloid status. Figure 2. Unadjusted CSF SNAP-25 and Ng as a function of amyloid status and APOE ε4 carrier status with confidence intervals. CSF SNAP-25 (A) and Ng (B) are significantly higher in cognitively normal participants who are amyloid-positive compared to amyloid-negativea. Even after adjusting for amyloid status, CSF SNAP-25 (C) is greater in APOE ε4 carriers than APOE ε4 noncarriers. CSF Ng (D) does not vary by APOE ε4 carrier status. aAmyloid-negative if CSF ptau181/Aβ42 < 0.0198; Amyloid-positive if CSF ptau181/Aβ42 ≥ 0.0198 (36) *, p < 0.05; **, p < 0.01; ***, p < 0.001; ****, p < 0.0001.
