marginal significancep = 0.021
Notably, the sex × TSD interaction for theta-ERS at Pz (congruent) and P4 (incongruent) approached marginal significance (Pz: p = 0.021; P4: p = 0.033), but post hoc tests confirmed no significant simple effects between sexes under pre-sleep or after-sleep conditions (all p > 0.05).
