From: Morphometric imaging biomarker identifies Alzheimer’s disease even among mixed dementia patients
The Apparently Healthy Controls (AHC) ranked in the increasing order of the MI biomarker signal, Ln(A/N), to establish the cut-off in a training study. The population data were ordered according to the Ln(A/N) signal starting with the lowest and ending with the highest value. A linear interpolation was made as X(N) + F * [X(N + 1) + X(N)], where X(N) is the Nth value, X(N + 1) is the N + 1th value, and F is the fractional reminder after taking 0.95 of X(N + 1). Based on this analysis, the cut-off is 6.98.
