Figure 2 The rise of von Willebrand factor over the first 48 h identified high-risk patients with a significant difference after univariate comparisons (p < 0.05) between patients with an end point and those free of end points at one-month follow-up. A similar trend was present for each parameter of the composite end point. Checkered bars = patients free of event at 30 days; Open bars = patients with an event at 30 days.
