What should I ask my team?

What is this trial trying to find out? What does the other group get, exactly? What are you measuring? What are the risks you know about, and what do you not know yet?

How many extra visits, and for how long? What do you pay back? What happens if I want to stop? If it works, do I keep getting it afterward? And the one people forget: who do I call at two in the morning?
