All changes can be seen under the relevant fields under the update date of 25/07/2008. 21/12/2007: Extensive updates were made due to a change in the protocol which has meant that there are now only two treatment arms: 1. ECT and pharmacotherapy 2. Pharmacotherapy alone All updates to this trial record due to this protocol change can be found under the date 21/12/2007. Please also note that the overall trial start date has also been updated. The previous overall trial start date was 01/11/2007. The trial title has also changed (as above). The previous trial title was 'Randomised controlled trial of ElectroConvulsive Therapy (ECT), pharmacotherapy or ECT and Pharmacotherapy combined in Relapse prevention after successful ECT for depression'.
