This biased towards certain subgroups who may, for distinction is useful in clarifying what is being whatever reasons, have no access to private care. For example a trial of different service Here recruitment is likely to be highly selective organisations (platforms) would be the UK 700 and potentially biased.

In contrast there are examples of therapy trials in To give an equivalent chance of a recruit being which a comparison was made between CBT in any of the groups in the trial design. Some plus routine care, supportive counselling plus researchers think that one of the purposes is routine care, and routine care alone for chronic to balance the groups on every factor that patients15 and acute patients.
