Wang 2006.

Methods	Allocation: randomised ‐ no further details Blindness: no further details Duration: 28 days
Participants	Diagnosis: schizophrenia (CCMD‐3), with aggressive behaviours according to scores of MOAS > = 4, or BPRS score > 38 History: no information n = 64 Sex: male and female Age: 31.15 years
Interventions	1. Magnesium valproate + risperidol: valproate 800‐1200 mg/d, risperidol 4‐6 mg/d, n = 32 2. Risperidol alone: 4‐6 mg/d, n = 32
Outcomes	Mental state: BPRS scores Behaviour: MOAS scores Adverse events Unable to use Adverse events: TESS ‐ no data reported
Notes	Data of this study apears to be very closely related to Wang 2005a, which was conducted by the same author one year earlier. Both studies measured exactly the same outcomes (Wang 2005a, n = 60; Wang 2006, n = 64), had the same inclusion criteria, with the same dosage of drugs. The numbers in the continuous outcomes are very similar. We suspect that Wang 2006 could be a follow up study of 2005, but we were unable to contact the author to verify.
