Selected health indicators with strong associations with EEG PSD. The charts show Pearson correlations (for binary variables, corresponding to point-biserial correlations) between relative log10 PSD and the self-reported diagnosis of atrial fibrillation, medication with zolpidem, SSRIs, and coumarin anticoagulants. Correlations that are significant after correction for FDR are marked with a circle with a color marking the appropriate channel and vigilance state
