Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Seroquel XR | Seroquel XR dose uptitrated starting from 300 mg in the evening on day 0, then increasing to 600 mg and up to 800 mg in the following two evenings. Previous antipsychotic was taken at the full dose on day 0, half dose on day 1 and stopped from day 2. From day 3 onwards it was possible to adjust the Seroquel XR dose, depending on the clinical response and tolerability of the patient, within the range of 400-800 mg per day | 12 | 107 | OG000 |
| Group 2 | Risperidone | Risperidone dose was uptitrated starting from 1 mg bid (morning and evening) on day 0, then increasing to 2 mg bid and up to 3 mg in the following two days. As per the other arm, previous antipsychotic was taken at the full dose on day 0, half dose on day 1 and stopped from day 2.
