Will I be told the results?

Ask on day one, because the honest answer is that many trials do not do this well. Trials can take years to report, and by then people have moved or been forgotten.

Ask for it in writing: will I get a plain-language summary, who sends it, and to what address. Then check that your team has written it down.
