Running a trial¶
Once a trial is recruiting you work from its overview rather than the setup wizard. This chapter covers what the overview shows and the controls available while a trial is live.
The overview at a glance¶
The overview brings together the trial’s status, its enrolment, and its participants:
Status: whether the trial is Recruiting, Not recruiting (recruitment closed), or Completed.
Enrolment plan: progress against the two recruitment gates.
Participants: counts by status (in screening, active, completed, withdrawn) and the ability to look at individuals.
Schema: the sequences and phases, and how participants are distributed across them.
Enrolment by arm¶
The Enrolment by arm panel shows, for each active/sham arm: how many participants are enrolled, how many have completed, its completion target, and its randomisation share. Above the table two figures track the gates:
Completed X / target: progress toward the irreversible stop.
Enrolled Y / limit: progress toward the reversible pause.
See Enrolment and randomisation for exactly how these behave.
Adjusting targets and the rate mid-trial¶
From this panel you can edit each arm’s completion target and the trial’s estimated completion rate while the trial runs, then save. The derived total and enrolment limit recompute immediately and the gates use the new values. Lowering a target below an arm’s current enrolment is allowed, targets are soft goals, so no confirmation is needed.
Participant statuses¶
Participants move through a sequence of statuses as they progress; withdrawals free a recruitment place, completions count toward the completion target. The full journey is described in Participants and the trial lifecycle.
Communications¶
The trial can send templated emails to participants at defined points (for example registration information). These are configured per trial and queued automatically as participants reach the relevant point.
