Further Methods for Meta-Analysis

Six further issues in meta-analysis are covered in this chapter to extend your knowledge. First, an alternative method to identify publication bias. Second, a special type of moderator analysis. Third, a method to identify the range of ‘true’ effect sizes in a random-effects meta-analysis. Fourth, a method to adjust for baseline differences between groups when computing effect size differences. Fifth, a better method for testing theory relationships. Finally, methods to address dependence among multiple outcomes. Not all these issues will be relevant in your meta-analysis; however, by covering a range of topics, I increase the chance of finding one you can use.
