The study from California’s Western University of Health Sciences in partnership with Ontario’s Institute for Clinical Evaluative Sciences (ICES) and Yale University in Connecticut was published in The New England Journal of Medicine on March 30, 2008 and demonstrates differences between the US in Canada with respect to the use of the drug.
