From the Editor |
Index terms: Editorials • Radiology (journal)
As of January 2001, we began review by statisticians of all manuscripts that have statistical content and that are to be published in Radiology (1). Although I believed, from its inception, this form of manuscript evaluation to be an essential component of the peer-review process, my belief has been further confirmed over the past many months. One of the most common comments by our statistical reviewers is that authors have selected inappropriate statistical tests for the analysis of their data. We urge authors to consult with statisticians regarding the analysis of their data. It is particularly important that a study be designed and data be collected in a manner that will allow the study hypothesis to be adequately evaluated. Statistical consultation in the study-planning stages can help ensure success in this regard.
With the November 2002 issue of Radiology, we begin a special series of articles that will appear in the section entitled Statistical Concepts Series. As I announced earlier this year (2), we are indebted to Kimberly E. Applegate, MD, MS, and Philip E. Crewson, PhD, for coordinating this series. Dr Applegate, an RSNA Editorial Fellow in the year 2000, is currently associate professor of Radiology and Health Services Research at Indiana University, Indianapolis. Dr Crewson, formerly director of Clinical Studies, Research Development, at the American College of Radiology, is currently assistant director of Scientific Development, Health Services Research, and Development Service at the Office of Research and Development, Department of Veterans Affairs, Washington, DC. Both Dr Applegate and Dr Crewson have expended a substantial amount of time and effort in selecting topics for this series, identifying the authors for the various topics, and working with the authors to ensure an appropriate level of depth of coverage for each topic without undue overlap with other topics in the series. After review of their manuscripts by Drs Applegate and Crewson, authors submitted the manuscripts to the Radiology Editorial Office for peer review.
We hope that authors, reviewers, and readers will find this series of articles helpful—authors with regard to the design of their studies and the analysis of their data, reviewers with regard to their evaluation and critique of manuscripts during the peer-review process, and readers with regard to improved understanding and interpretation of articles published in Radiology. Since we have established the section title Statistical Concept Series for these articles, they will be accessible through Radiology Online (radiology.rsnajnls .org) by clicking first on Browse by Subspecialty and Category (Radiology Collections) and second on this section title. As noted by Drs Applegate and Crewson in their article "An Introduction to Biostatistics," the first in this series and published in the current issue of the Journal (3), "These articles are meant to increase understanding of how statistics can and should be applied in radiology research so that radiologists can appropriately interpret the results of a study."
