Table 2: Clinical and biochemical data of the studied groups. Within the mixed group, no difference was noted between mixed with vascular disease and mixed with Lewy body disease regarding age, disease duration, MMSE, A\(\beta\)42, \(\tau_{\text{P-181}}\), and \(\tau_{\text{T}}\). After correction for multiple comparisons, only the logopenic subgroup showed a trend towards significantly higher median [quartiles] levels of \(\tau_{\text{P-181}}\) [103 (97-203) pg/mL] compared to typical AD (\(p\) = 0.076). No significant difference was observed in any of the studied parameters between mixed with vascular and mixed with LB subgroups or among posterior, frontal, and logopenic subgroups (Figure 2).
