Factors Associated with Outcomes of Percutaneous Transluminal Renal Angioplasty in Patients with Renal Artery Stenosis: A Retrospective Analysis of 50 Consecutive Cases

Table 3

Univariate analysis of predictive and confounding factors for regression of eGFR. A: all subjects; B: atherosclerotic RAS only; BP: blood pressure; BMI: body mass index; IGT: impaired glucose tolerance; DM: diabetes mellitus; RI: resistive index; eGFR: estimated glomerular filtration rate. Regression of eGFR was calculated as log (eGFR y1) − log (eGFR y0). Linear regression analysis, other parameters were analyzed with the unpaired -test. Plasma renin activity and eGFR were analyzed after log conversion.
