J Am Coll CardiolPublished

  • Randomised controlled trial
  • prospective
  • sham-controlled
  • patient- and assessor-blinded
  • 56 clinical centers worldwide
  • Bayesian trial design

Authors' conclusion

There was no significant difference between groups in the primary analysis. However, multiple secondary endpoint analyses favored RDN over sham control.

Study context

Population
Patients with uncontrolled hypertension prescribed 1 to 3 antihypertensive medications
Participants
