^*eGFR trajectory for 6–12 months leading up to renal artery revascularization.

^**eGFR trajectory from renal artery stent placement up to 6–12 months follow-up.

^†eGFR trajectory from renal artery stent placement up to 6–12 months follow-up among patients with eGFR <40 ml/min/1.73m². Among patients with an eGFR at post-intervention <40 ml/min/1.73m², the hazard ratio is for a one unit increase in eGFR, up to 40 ml/min/1.73m².

CKD=chronic kidney disease; ACEI=angiotensin-converting-enzyme inhibitor; ARB=angiotensin receptor blocker; CI=confidence interval.
