Difference in Chitinase-3-like protein 1 (CH3L1 aka YKL-40) is comparable with the change observed for Aβ
, tau and p-tau
in AD vs. aged cognitively-normal controls (age > 60y) (linear regression, **p = 0.001-0.01, ***p < 0.001). Control, green-circle, MCI blue-square, AD red-triangle. A. CH3L1, B. Aβ42, C. total tau, D. p-tau181.
