CI: cognitively impaired; HC: healthy controls; ROI: region of interest; SD: standard deviation; R: right; L: left; NS: not significant.

Differences in relative powers in 10 deep gray matter structures between CI and HC groups, ranked by effect size and, in case of equal effect size, significance. Depicted are the mean relative power values for each ROI in the alpha2, alpha1, and theta band for the CI and HC group, since group differences were only significant in these power bands. Analyses were corrected for age, gender, and multiple comparisons over regions (correcting for 10 regions times six frequency bands plus peak frequency). Significant regions are printed in bold and italics. Depicted are both significant p-values as well as p-values < 0.1 to show the trend across the majority of deep gray matter structures.
