After the 12 month interim analysis the study team and a trial steering group made of 3 independent member (a statistician, a mental health specialist and a clinical researcher) will review the data, and if there is no harm seen all of those on the control arm will be offered Call for Life Lite, which provides weekly adherence calls and appointment reminders only, as we plan to offer Call for Life Lite to all patients in the clinic by this time. Those on the full Call for Life arm will continue on this arm. If a positive benefit is seen full Call for Life will be offered to all in the clinic (as long as there are sufficient funding to allow for the phone connection aspect of the tool).
