Approximately 1000 potentially relevant references were identified, a number of them from education, psychology and sociology.
After briefly reviewing the procedural methods required to carry out a review, and the basic statistical methods used to combine study estimates, less established methods are discussed.
These include methods for dealing with publication bias, meta-regression, meta-analysis of individual patient data, the synthesis of non-randomized evidence alone and in combination with randomized studies, Bayesian modelling and economic evaluation through meta-analysis.
