The comparison of the power-law characteristics for the eldBETA, the BETA, and the Benchmark databases. (Upper left) Bar plot of the negative of the power-law exponent for the three databases with different montages. (Bottom left) The channel location corresponding to each montage. The asterisks indicate a statistically significant difference between the pairs. *\(p < 0.05\), **\(p < 0.01\), ***\(p < 0.001\), Bonferroni corrected. (Upper right) The power spectrum (solid curves) with the associated power-law fitting (dashed curves) for the three databases. The shaded area indicates a statistical significance (\(p < 0.05\)) between the three databases as assessed by one-way RMANOVA. Green: the eldBETA database; Brown: the BETA database; Blue: the Benchmark database. (Bottom right) Bar plot of the age distribution for the three databases. (Best view in color).
