Participant Flow

Recruitment occured at the University of Colorado Hospital beginning September 1, 2011 and ended on October 4, 2011.

There were 8 subjects that were excluded from trial before assignment to groups; 5 due to personal reasons, 2 due to elevated bilirubin, and 1 due to elevated serum creatinine.
