Only pathology-related PTMs are displayed, i.e. the ones whose abundances (AUC) were significantly higher in a disease group than in CTL (FDR adjusted Kruskal–Wallis’s P < 0.05). The table shows the result of the post-hoc Wilcoxon’s pairwise group comparisons on PTMs (+/−P < 0.05; + +/- -P < 0.005; + + +/− − −P < 0.0005). All statistical tests were two-tailed. Source data are provided as a Source Data file (see sheet 5 for the exact P values). Plus sign and Minus sign represent either a significant increase or significant decrease, respectively, in the condition at the top position of the panel heading. PTMs with p-values in bold font are those specific for AD (insoluble tau Ub-K311 and P-S262; soluble tau Ub-K311, Ub-K317 and P-S262+Ub-K267), for 4R-tauopathies (insoluble tau Ub-K369; soluble tau Ub-K343 and Ub-K369) and for 3R-tauopathies (insoluble tau Ac-K311 and Me-K331; soluble tau Ac-K311). PTMs are numbered according the full-length (2N4R) tau protein. AD Alzheimer’s disease (n = 15), CBD corticobasal degeneration (n = 5), PiD Pick’s disease (n = 5), FTLD frontotemporal lobe degeneration (n = 10, including FTLD-4R, n = 4 and FTLD-3R, n = 6); control subjects, CTL (n = 5).
