ADVICE

Use Ethical, Realistic Controls

Controls must receive standard-of-care guidance, not harmful or trivial comparators.
Ensure fair comparators for lifestyle or diet trials to avoid biased effects.

Store blood samples centrally and require event reporting to detect adverse patterns across teams.
