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.
