Abstract
We recently became aware of an error in the classification of one study subject's positive treatment response status at the end of the post-continuation phase of this study. We originally reported that all 5 subjects who achieved depressive symptom remission during the acute phase of the study (and thus received 4 weekly continuation phase ketamine infusions) were classified as responders at the end of the post-continuation phase. However, one of these 5 subjects was misclassified as a positive treatment responder at the end of the post-continuation phase. Therefore, only 4 of these 5 patients were positive treatment responders at the end of the post-continuation phase. Although our main conclusions are not changed, we believe that it is our responsibility to report the error and updated results. The authors would like to apologise for any inconvenience caused.
