Table 2:

Significant correlations of sleep EEG power and coherence with clinical measures including all patients. For every correlation, the range of r- and p-values with the number of significant electrodes in brackets are reported. Ranges for positive and negative r-values and the corresponding p-values are depicted separately (only applicable for NREM Sigma Peak Coherence and SAPS Sum). NREM: non-rapid eye movement sleep; CGAS: Children’s Global Assessment Scale (higher score means better overall functioning, i.e. 100 = Superior functioning, 50 = Moderate degree of interference in functioning, 10 = Needs constant supervision); SAPS: Scale for the Assessment of Positive Symptoms (0 = None/Not at all, 1 = Questionable, 2 = Mild, 3 = Moderate, 4 = Marked, 5 = Severe; 34 items).
