Poor reporting of research hampers assessment and makes it lessuseful. An international group of methodologists, researchers,and journal editors sets out guidelines to improve reports ofobservational studies

Much biomedical research is observational. The reportingof such research is often inadequate, which hampers the assessmentof its strengths and weaknesses and of a study's generalisability.The Strengthening the Reporting of Observational Studies inEpidemiology (STROBE) Initiative developed recommendations onwhat should be included in an accurate and complete report ofan observational study. We defined the scope of the recommendationsto cover three main study designs: cohort, case-control andcross-sectional studies. We convened a 2-day workshop in September,2004, with methodologists, researchers, and journal editorsto draft a checklist of items. This list was subsequently revisedduring several meetings of the coordinating group and in e-maildiscussions with the larger group of STROBE contributors, takinginto account empirical evidence and methodological considerations.The workshop and the subsequent iterative process of consultationand revision resulted in a checklist of 22 items (the STROBEstatement) that relate to the title, . . .
