Full factorial mixed models were run for AVG, Cz, and LM separately with BDI-II group and biological sex as centered between-subjects variables, whereas day and channel were within-subjects variables. EEG asymmetry score was again the dependent variable. Although no main effect of BDI group emerged for AVG, Cz, or LM (all p > .22), a BDI group by sex interaction emerged for AVG (F(2, 300) = 4.5, p = .01), Cz (F(2, 300) = 3.8, p = .02), and LM (F(2, 300) = 8.4, p < .001), so follow-up mixed models were run for each sex separately to examine BDI-II group differences. Cohen's d is reported for significant differences between BDI-II depression groups.5
