The Resistive Index Is a Marker of Renal Function, Pathology, Prognosis, and Responsiveness to Steroid Therapy in Chronic Kidney Disease Patients
Figure 6
Kaplan-Meier analysis of patients with different levels of RI stratified by steroid administration. The patients in the high-normal RI group showed good response to steroids. However, in the high RI group, steroid therapy did not significantly improve renal survival. The 3-year renal survival rates with and without steroid therapy were 0.982 and 0.947, respectively, () in the normal RI group; 0.957 and 0.682, respectively, () in the high-normal RI group; and 0.600 and 0.684, respectively, () in the high RI group.
