V. Agosti, THE EFFICACY OF CONTROLLED TRIALS OF ALCOHOL MISUSE TREATMENTS IN MAINTAINING ABSTINENCE - A METAANALYSIS, International journal of the addictions, 29(6), 1994, pp. 759-769
Meta-analysis was used to establish the efficacy of various controlled
alcohol misuse treatments in maintaining abstinence over short-term,
6-month, and 12-month follow-ups. Effect sizes were measured by odds r
atio. Aggregate effect size differences between experimental and contr
ol groups were negligible. Only three of 15 studies found a clinically
significant difference between treatment abstinence outcomes.
