1 Comparison of descending phlebography with quantitative photoplethysmography, air plethysmography, and duplex quantitative valve closure time in assessing deep venous reflux  Harold J. Welch, MD, Eleni C. Faliakou, MD, Robert L. McLaughlin, RVT, Susan E. Umphrey, RVT, Michael Belkin, MD, Thomas F. O'Donnell, MD  Journal of Vascular Surgery  Volume 16, Issue 6, Pages (December 1992) DOI: / (92)90054-C Copyright © 1992 Society for Vascular Surgery and the North American Chapter, International Society for Cardiovascular Surgery Terms and Conditions

2 Fig. 1 Receiver operating characteristic (ROC) curves for noninvasive tests for deep venous reflux. TVCT is best test by receiver operating characteristic, and greater than or equal to 4 seconds is optimal value for that test. PV, Popliteal vein (vein closure time).
