SLC6A3 and mood disorder: We performed similar analyses excluding participants with the mood disorders (N = 4), with the DAT x COMT interaction now at F(2, 65) = 5.99, p = .004, partial Eta2 = .17, a main effect for COMT, F(2,65) = 3.77, p = .03, partial Eta2 = .11, and no main effect for DAT, p > .93.
