Figure 2From: Renal arterial resistive index is associated with severe histological changes and poor renal outcome during chronic kidney disease Association of RI with histological parameters. Boxes show the first and third quartiles, with the median as a thick line. Whiskers extend to minimum and maximum values. A: RI according to arteriolosclerosis, defined as the presence of hyaline deposits in the wall of at least one preglomerular arteriole. B: RI according to maximal intima thickness (moderate arteriosclerosis was defined as a thickening of intima with intima/media ratio < 1 and severe arteriosclerosis as an intima/media ratio ≥ 1). * p<0.05 versus normal and intima/media<1. C: RI according to interstitial fibrosis. * p<0.05 versus interstitial fibrosis<20%.Back to article page
