Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients were recruited from psychiatric emergency units from 3 hospitals located in the metropolitan area of Barcelona, Spain.
Eligible subjects met inclusion criteria and did not meet exclusion criteria.
Allocation was performed by the psychiatrist's in charge of the patient's inclusion and consisted in contacting by phone the holder of the allocation procedure at a central administration site. Patients were immediately randomized to antipsychotic treatment to haloperidol, olanzapine, risperidone, quetiapine, or ziprasidone.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer generated randomization followed a 1:1:1:1:1 procedure into the 5 treatment groups.
