Number of outcome results by group. The pie chart shows the number of outcome results by outcome group. Note that the number of outcomes exceeds the number of studies included, because some studies examined more than one outcome. The greatest number of outcomes was measured for drug use/addictive behavior, followed by academic, antisocial behavior, social function, occupation, self-esteem, driving, services use, and obesity outcomes.
