Univariate and multivariate tests to evaluate for a relationship between beta power and group and duration seizure‐free

	Dependent variable	Univariate beta power	Univariate age	Multivariate beta power + age
Logistic regression	Healthy control versus BECTS	p = 0.887 (wake)	p = 0.185
		p = 0.030 (sleep) a	p = 0.846
Linear regression	Duration seizure‐free	p = 0.008 (wake)	p = 0.003	Beta p = 0.014 b
		p = 0.011 (sleep)	p = 0.011	Beta p = 0.027 a

Unadjusted p‐values (column 2) and, when appropriate, adjusted p‐values accounting for age (column 3) are reported.

^aSignificant value in an a priori test.

^bPossible relationship identified in exploratory testing
