Interventions | (1) Oxcarbazepine low dosage, 28 participants; (2) oxcarbazepine full dosage, 29 participants; (3) naltrexone, 27 participants Drug dose: oxcarbazepine low dosage, 600 to 900 mg/d; oxcarbazepine full dosage, 1500 to 1800 mg/d; naltrexone 50 mg/d All participants were offered a supportive self‐help group alternatively run by counsellors and psychologists, with a frequency of two days per week for the duration of the study Setting: outpatient Duration: 12 weeks.

Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Low risk | Computer‐generated system used. Random assignment achieved in a non–centre‐specific manner with an interactive voice‐response central randomisation service. Random assignment stratified according to the presence of a co‐morbid psychiatric diagnosis |
Allocation concealment (selection bias) | High risk | Open study |
Incomplete outcome data (attrition bias) All outcomes | Low risk | Quote: "Primary and secondary efficacy analyses were performed on the intent‐to‐treat population, which included all randomly assigned patients who took at least one dose of study medication." To take care of missing data, the last observation carried forward method was also applied |
Blinding of participants and personnel (performance bias) all outcomes | High risk | Unblinded study |
Blinding of outcome assessment (detection bias) subjective | High risk | Unblinded study |
Blinding of outcome assessment (detection bias) objective | Low risk | Outcome measurement not likely to be influenced by lack of blinding |
