Change Type: Clarification
Change Details: This Editorial originally made reference to the fact that the mice in the experiments showed no visible sign of distress. That statement referred only to the animals for which the data were not withdrawn. The committee did not comment on whether or not the animals in the withdrawn experiments showed distress. For clarity, the statement has now been removed.
