Figure 4From: Renal arterial resistive index is associated with severe histological changes and poor renal outcome during chronic kidney disease Kaplan Meier curves of renal survival according to baseline RI. Renal function decline is defined as decrease in eGFR of at least 5mL/min/1.73m2/year or need for RRT. Plain line represents patients with RI < 0.65 and dotted line those with RI ≥ 0.65; p = 0.0005, log-rank test.Back to article page
