People admitted to the emergency room of Instituto Philippe Pinel, Rio de Janeiro, Brazil, whose aggression/agitation was thought due to psychosis and for whom staff were unsure if best to restrict using physical restraints or a seclusion room, were randomly allocated to one or the other and followed up to 14 days. The primary outcomes were 'no need to change intervention early - within 1 h' and 'not restricted by 4 h'.
