Table 6 Results of the group-wise LMM analysis performed to evaluate change in temporal EEG measures over time (in months) in Aβ + MCI or AD dementia patients. Regression coefficients (β) and 95% confidence intervals (CI) of the Time effects are reported. Estimates for the Group*Time interaction effects, as well as estimates adjusted for age, sex, and medication use are presented in Additional file 2 (Table S5)
