Figure 3. Association of Ex Vivo Antithrombin Supplementation With Anti–Factor Xa (Anti-FXa) Levels and Peak Thrombin Generation Among Never Responders.

Plasma from patients identified as never responders was supplemented with antithrombin to achieve a final activity of 120%, 150%, or 180%, and associations with anti-FXa levels and thrombin generation compared.
