Following ANOVA analysis, results revealed a main effect of dipole site on dipole P300 amplitude (F(1,94) = 21.15, P < 0.001). Namely, the temporal dipoles resulted in greater P300 amplitude than the frontal dipoles, and the effect was strongest in patients with anxiety disorder (F(1,94) = 32.15, P < 0.001) and weakest in patients with depressive disorder (F(1,94) = 7.85, P < 0.01). The effect was intermediate for the healthy control group (F(1,94) = 18.15, P < 0.001).
