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

Table 4

Multivariate linear regression analysis of predictive and confounding factors for regression of eGFR. A: all subjects (); B: atherosclerotic RAS only (); BMI: body mass index; RI: resistive index; eGFR: estimated glomerular filtration rate. eGFR was analyzed after log conversion. Regression of eGFR was calculated as log (eGFR y1) − log (eGFR y0).
