Resting state EEG power spectrum and functional connectivity in autism: a cross-sectional analysis

Table 2 P values from the univariate statistics (training dataset, 147 ASD and 140 NT)

	Differences in mean		Differences in variance
Alpha peak frequency	0.77 (d = − 0.11)		0.12
Reactivity to eye opening	0.042 (d = − 0.18)		0.76

	Eyes open	Eyes closed	Eyes open	Eyes closed
Absolute alpha power	0.43 (d = − 0.05)	0.39 (d = − 0.20)	0.37	0.28
Power spectrum	0.72 (d = − 0.05)	0.91 (d = 0.27)	0.53	0.92
wPLI	0.90 (d = − 0.24)	0.98 (d = − 0.05)	0.89	0.23
OrthPowCorr	0.59 (d = − 0.15)	0.91 (d = 0.12)	0.39	0.85

P values were obtained after comparing the log-likelihoods of the three linear mixed effects models (see Materials and Methods). For power spectrum, wPLI and OrthPowCorr, p values were derived from cluster-based permutation tests. Cohen’s d values are given for reference after the p values, but note that they do not directly reflect statistical significance, since they were computed with the raw EEG parameters and do not correct for any covariates. wPLI: Weighted phase lag index. OrthPowCorr: Orthogonalized power correlations. P values under 0.05 are highlighted in bold
