Ketamine vs Electroconvulsive Therapy in the Management of Treatment-Resistant Depression

Notice of Correction 2/7/25: In Figure 1A (MADRS section only) and Figure 1B, the SD, SMD, and 95% CI values in the Anand, Total, and Heterogeneity rows have been corrected.In the first sentence of the Results, the total and subset numbers of patients have been corrected.To reflect the data corrections, changes have been made to the Results section and the first and last paragraphs of the Discussion to clarify that the findings, consistent with an earlier study, indicate that ECT may be superior to ketamine for improving depression severity in the acute phase, but treatments did not significantly differ in terms of response and remission as outcomes.
