Condition Number of Subjects Male/ Female Age (Years, Mean ±SD) MMSE (Points, Mean ±SD) Immuno positivity percentage (median, min -max)
PHF AT8
Healthy 17 6/11 72 ± 14 29.4 ±1.4 38(9-58) 0.6 (0.4-1.7)

Table 1: Significant differences among groups were found in MMSE scores and % immunopositivity for AT8. Ap<0.001 as compared with the control group, Bp<0.001 as compared with the AD group. ANOVA followed by Tuckey test for the variables age and MMSE. Kruskal-Wallis followed by Mann-Whitney U-test for immunopositivity percentages.
