Comparison of the effects of open and endovascular aortic aneurysm repair on long-term renal function using chronic kidney disease staging based on glomerular filtration rate

Kaplan Meier life-tables: renal function decline, OR vs EVAR. A, Plot for entire series: renal function decline defined as progression to chronic kidney disease (CKD) stage 3 or higher for patients without baseline CKD or >20% glomerular filtration rate (GFR) decline for patients with pre-existing CKD. B, Renal function decline after abdominal aortic aneurysm AAA repair for patients without pre-existing CKD. C, Renal function decline after AAA repair for patients with pre-existing CKD.
