Note
Pathologic mild and moderate to severe CKD groups are divided based on all scores in four kidney biopsy pathology parameters (glomerulosclerosis, arteriosclerosis, IF/TA, and interstitial inflammation). A pathologic mild CKD (Mild CKD) is for those with no grade 3 and < 2 of grade 2; and pathologic moderate to severe CKD is for those with at least 2 of grade 2 or 1 of grade 3. EDV, end diastolic velocity; p-intensity, pixel intensity; PSV, peak systolic velocity; SWV, shear wave velocity.
No significant difference in resistive index between healthy control and pathologic mild CKD, or between pathologic mild CKD and pathologic moderate to severe CKD.
