The first step in joining ASCEND PLUS is to complete the screening questionnaire. If the answers on your screening questionnaire suggest that the study is suitable for you, we will tell your GP you are planning to join the study and ask them to contact the coordinating centre if they have any concerns.

If we don’t hear about any concerns from your GP, you will be asked to complete the ‘randomisation’ questionnaire.  If you still wish to join the study and your answers to this second questionnaire suggest that the study is suitable for you, you will be ‘randomised’ into the study. This is where the computer selects which treatment you get for the rest of the study and we will tell your GP that you have joined the trial.
