The marked difference in alpha between nonresponders and responders contrasts with the lack of differentiation between mono- and dual-therapies, evident in Fig. 2B. The exploratory ANOVA in patients (i.e., Response Group and Treatment as between group factors; Age covariate) replicated the Condition × Response Group effect, F[1,36] = 7.23; p = .011, but revealed no significant effects or interactions involving Treatment.
