The Resistive Index Is a Marker of Renal Function, Pathology, Prognosis, and Responsiveness to Steroid Therapy in Chronic Kidney Disease Patients

Figure 1

Changes in kidney sizes based on chronic kidney disease (CKD) stages. The renal length was significantly smaller in patients with CKD stage 5 than in those with CKD stage 1 or 2 (𝑃<0.01). However, in CKD stages 1 to 4, there was no clear association between the disease stage and kidney size. *𝑃<0.05 versus stage 1, ^†𝑃<0.05 versus stage 2.
