The primary composite end point at the early clinical evaluation (82.3% with oritavancin
and 78.9% with vancomycin), the end point of clinical cure at post-therapy evaluation as assessed
by a study investigator (79.6% and 80.0%, respectively), and the end point of a reduction in
lesion size of 20% or more at early clinical evaluation (86.9% and 82.9%, respectively) met the
prespecified noninferiority margin, since the lower limit of the 95% confidence interval for the
between-group difference (oritavancin vs. vancomycin) was above −10 percentage points (Fig. 2).
