  1. The table summarises the results of linear regression and percentage difference calculations for all analytes assayed in this study. Linear regression used the median values of the measurements made at each transfer step. ‘% change’ represents the average of the percentage difference between each of the relevant number of transfer steps. Bold text is used as a visual aid and has no other meaning. Aβ, amyloid beta; AD, Alzheimer’s disease; CTRL, control, T-tau, total tau.
