1/13 • Adverse events were collected for the duration of the study (October 11, 2012 to July 25, 2013). This analysis group includes all participants exposed to the test product.
At each visit, after the subject had the opportunity to spontaneously mention any problems, the investigator inquired about AEs by asking the standard questions, "Have you had any health problems since your last study visit? Have there been any changes in the medicines you take since your last study visit?"
