“Preferred Reporting Items for Systematic Reviews and Meta-Analyses: The PRISMA Statement”, 2009-07-21 (; backlinks; similar):
In 1996, to address the suboptimal reporting of meta-analyses, an international group developed a guidance called the QUOROM Statement (QUality Of Reporting Of Meta-analyses), which focused on the reporting of meta-analyses of randomized controlled trials8. In this article, we summarize a revision of these guidelines, renamed PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses), which have been updated to address several conceptual and practical advances in the science of systematic reviews…A three-day meeting was held in Ottawa, Canada, in June 2005 with 29 participants, including review authors, methodologists, clinicians, medical editors, and a consumer. The objective of the Ottawa meeting was to revise and expand the QUOROM checklist and flow diagram, as needed.
Conceptual Issues in the Evolution from QUOROM to PRISMA:
Completing a Systematic Review Is an Iterative Process
Conduct and Reporting Research Are Distinct Concepts
Study-Level Versus Outcome-Level Assessment of Risk of Bias
Importance of Reporting Biases
…The new PRISMA checklist differs in several respects from the QUOROM checklist, and the substantive specific changes are highlighted in Table 2. Generally, the PRISMA checklist “decouples” several items present in the QUOROM checklist and, where applicable, several checklist items are linked to improve consistency across the systematic review report.
