3 Figure 2 Postoperative course of (A) INR, (B) aPTT, and (C) serum LDH levels during the first postoperative 2 weeks. The horizontal line in the middle of each box indicates the median; the top and bottom borders of the box mark the 75th and 25th percentiles, respectively; and the whiskers mark the 90th and 10th percentiles. INR, International normalized ratio; CVA, cerebrovascular accident; LVAD, left ventricular assist device; aPTT, activated partial thromboplastin time; LDH, lactate dehydrogenase.
