Table 2 Univariate analysis of parameters associated with renal function decline at 18 months (defined as a decrease in eGFR of at least 5 mL/min/ 1.73 m 2 /year or need for RRT) (Mann–Whitney and Fisher’s exact tests)

From: Renal arterial resistive index is associated with severe histological changes and poor renal outcome during chronic kidney disease
