Osaka City University
In the summer of 2013, two Japanese universities retracted several publications of clinical trials that purported to show that Valsartan (branded as Diovan) had cardiovascular benefits, when it was found that statistical analysis had been manipulated, and that a Novartis employee had participated in the statistical analysis but had not disclosed his relationship with Novartis but only his affiliation with Osaka City University, where he was a lecturer.
