MedicalResearch.com Interview with: Steven Woloshin, MD MS Professor of The Dartmouth Institute Professor of Medicine Professor of Community and Family Medicine The Center for Medicine in the Media Dartmouth Institute for Health Policy and Clinical Practice Lebanon, New Hampshire MedicalResearch.com: What is the background for this study?
