  1. Each row shows the results for a regression model using the criterion as the predicted variable and alpha power and the frequency of the peak as the predictor variables. Coefficients for each predictor are listed. The right part shows p values for each significant coefficient and ‘NS’ stands for not significant after FDR (q = 0.1); MMSE, Mini Mental State Examination; TMTA, Trail-Making Test part A; TMTB, Trail-Making Test part B; BNT, Boston Naming Test.
