An independent data and safety monitoring
committee reported to the executive committee.
It regularly assessed safety outcomes, overall study
integrity, and study conduct, at intervals based on
the number of patients who had completed the
90-day treatment period throughout the trial, and
oversaw a single interim analysis. An independent
clinical-event adjudication committee, the members
of which were unaware of the treatment assignments,
adjudicated the primary and secondary
efficacy end points and all bleeding events
that were not reported as minimal.
