Note
*
M-CKD, Pathologic moderate to severe CKD is defined as at least 2 of grade 2 or 1 of grade 3 based on all scores in four kidney pathology parameters. AUROC, the area under the receiver operating characteristics; EDV, end diastolic velocity; Max-PI, maximal pixel-intensity; Min-PI, minimal pixel-intensity; PSV, peak systolic velocity; RI, resistive index; SWV, shear wave velocity.
