Fig 1 Flow diagram of included patients and subgroups. CA, Celiac artery; CMS, chronic mesenteric syndrome; SMA, superior mesenteric artery. Journal of Vascular Surgery 2013 57, 1603-1611.e10DOI: (10.1016/j.jvs.2012.11.120) Copyright © 2013 Society for Vascular Surgery Terms and Conditions

Fig 2 Receiver operating characteristic (ROC) curve comparing the peak systolic velocities (PSV) for the celiac artery (CA) with a 70% stenosis during expiration is shown. The ROC curve is created by plotting the percentage of actual positives, which are correctly identified as such (sensitivity) against the percentage of negatives, which are correctly identified (specificity), at several PSV threshold settings. AUC, Area under the curve; EDV, end-diastolic velocity.
