Fig 1 Graph analysis (nonlinear regression) for the association of the adenosine diphosphate (ADP) test and postoperative bleeding. The Annals of Thoracic Surgery 2011 91, 123-129DOI: (10.1016/j.athoracsur.2010.09.022) Copyright © 2011 The Society of Thoracic Surgeons Terms and Conditions
Fig 2 Receiver operating characteristic curve analysis for excessive bleeding prediction by the ADP test. The best predictive value corresponds to an ADP value of 307 (sensitivity 72%, specificity 66%). (ADP = adenosine diphosphate; AUC= area under the curve; c.i. = confidence interval.)

Fig 3 Adenosine diphosphate (ADP) test pattern distribution in the study population. The ADP values of 14 patients with excessive bleeding (•) are reported in the upper panel. Ten out of 14 patients with major bleeding have an area under the curve less than 307.
