title: A new title to an old song: some observations on the conduct of meta-analyses.
abstract: The purpose of this commentary is to draw attention to some unsatisfactory features in the way that meta-analyses are presented in assisted reproduction journals. These features will be illustrated with reference to recently published papers. An appeal will be made for a more fastidious and rigorous approach to this statistical technique that has become a ubiquitous part of the research effort in assisted reproduction treatment.
