Pyschotic MDD patients had a superior response to ECT than rTMS (73.3 vs.27.5% reduction in HRSD, p = 0.005). Non-psychotic patients showed comparable reduction with ECT and rTMS (44.8 vs 53.2%). The degree of symptomatic improvment in non-psychotic patients was unusual for an ECT trial |

ECT was superior to rTMS in multivariate analyses across depression measures (p = 0.04), with the diffrent most market for the Beck Depression Inventory (BDI)(69.1 vs 45.5% improvment, p = 0.03). HOwever, no difference noted on change in HRSD. An equivalent number of patients in each group (11 of 16) achieved remission criteria (final HRSD < 8). |

ECT and rTMS were equivalent in efficacy in all deoression measures. 12 of 20 ECT patients met response critiria (52% descrease in HRSD or a final rating < 10 and final GAF < 60; 11 of 20 rTMS patients met response criteria. As in the previous study by Grunhaus et al.(2000) the degree of impronement was unusually ioe for an ECT sample. |
