Webdiagnosed by no ﬂow in the renal artery. We have included two analyses. 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.
