In 2007, Marcia Angell, former editor-in-chief of the "New England Journal of Medicine" and a lecturer in social medicine at the Harvard Medical School, said in "Stern", a German-language weekly newsmagazine, that AstraZeneca's scientists had misrepresented their research on the drug's efficiency, saying "Instead of using presumably comparable doses each drug, the company's scientists used Nexium in higher dosages. They compared 20 and 40 mg Nexium with 20 mg Prilosec. With the cards having been marked in that way, Nexium looked like an improvement – which however was only small and shown in only two of the three studies."
