The Cochrane Methodology Register (CMR) is a bibliography of publications that report on methods used in the conduct of controlled trials. It includes journal articles, books, and conference proceedings, and the content is sourced from MEDLINE and hand searches. CMR contains studies of methods used in reviews and more general methodological studies that could be relevant to anyone preparing systematic reviews. CMR records contain the title of the article, information on where it was published (bibliographic details), and, in some cases, a summary of the article. They do not contain the full text of the article.
The CMR was produced by the Cochrane UK, until 31st May 2012. There are currently no plans to reinstate the CMR and it is not receiving updates.* If you have any queries, please contact the Cochrane Community Service Team (support@cochrane.org).
The Publishers, John Wiley & Sons Ltd, thanks Update Software for the continued use of their data formats in the Cochrane Methodology Register (CMR).

| Abstract | There is a persistent and widely held belief -- referred to as the "tie-score effect" or the "dodo bird verdict" -- that different types of intervention have equivalent outcomes. However, the research supporting this belief has been limited largely to comparing methods drawn from different schools of psychotherapy with emphasis on treatment of the emotional problems of adults. A review of relevant meta-analyses published in the past decade (n = 31) was undertaken to determine whether this verdict applied to the broader range of problems and interventions typically found in clinical social work. The majority of these meta-analyses reported differential effects associated with different types of interventions. There proved to be little basis for extending the dodo's verdict to the range of problems and interventions of concern to social workers. Moreover, several patterns of differential effectiveness occurred that could help guide the practitioner's choice of interventions. (57ref) |
