Description of intervention(s) / exposure
Patients were randomized to open-label antipsychotic treatment with the following dose ranges: olanzapine 7.5-40 mg/day, risperidone 1.5-7.0 mg/day, quetiapine 100–1500 mg/day, and ziprasidone 40–240 mg/day. Study medication was administered orally with the doses prescribed at the treating psychiatrist's discretion. Participants randomized to each second generation antipsychotic received the assigned antipsychotic for 12 months on a daily basis.

Allocation to intervention
Randomised controlled trial
Query!
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.

A computer generated randomization followed a 1:1:1:1:1 procedure into the 5 treatment groups.

Summary
Brief summary
The goal of this study was to perform a pragmatic, open, randomized clinical trial comparing the 12-month effectiveness (measured by time to discontinuation) of several second-generation antipsychotic drugs, with that of low doses of haloperidol in never-treated FEP. Method: 150 patients were randomized to open-label antipsychotic treatment with haloperidol, olanzapine, risperidone, quetiapine, and ziprasidone. Retention of patients on treatment was considered a measure for effectiveness (primary outcome measure). Secondary outcomes included symptom change by antipsychotic as measured by the Positive and Negative Syndrome Scale (PANSS).
