Our main analysis includes occlusion in the “greater than” groups so that it is those that have no ﬂow or a PSV equal to or greater than a speciﬁc velocity (eg, no ﬂow or a PSV 285 cm/s for 60% RAS). Another analysis is included where the occlu-sions were excluded. WebMultiple regression analysis confirmed the age dependence of the S/D ratio, PI, and RI of the renal artery in normal children.
