Change in systolic BP at 2 years for subgroups. Significant SBP reductions were observed at 2 years post RF RDN in patients with CKD (A), T2DM (B), OSA (C) and in patients ≥65 years of age (D). There were no significant differences between patients with and without CKD, T2DM or OSA or between younger vs older patients. All SBP changes from baseline are significant (p < 0.05) expect the nighttime drop for patients with CKD
