Notes  
Risk of bias
Bias Authors' judgement Support for judgement
Adequate sequence generation? Unclear risk Methos of sequence generation not reported
Allocation concealment? Low risk "Pharmacy staff of the Pavlov University prepared naltrexone and placebo in identically appearing capsules containing a riboflavine marker. A Amaster code was kept art Pavlov so the blind could be broken in case of emergency. Medication were dispensed double blind at each counselling session"
Blinding? 
 objective outcomes Low risk double blind; naltrexone and placebo in identically appearing capsules containing a riboflavine marker.
Blinding?
