This PDF file includes:

  • Materials and Methods
  • Fig. S1. Platelet reactivity is not altered under OTI compared to VKA treatment and nonanticoagulated blood.
  • Fig. S2. Adhesion size categories are characterized by area size and thrombus volume.
  • Fig. S3. Prothrombotic effects of OTI are found under CTI anticoagulation and are independent from OTI plasma concentration.
  • Fig. S4. Inhibition of GPIbα-vWF interaction reduces thrombus formation on plaque material under arterial flow conditions.
  • Fig. S5. IL-4R/GPIbα-tg chimeras have normal platelet counts and lack GPIbα surface expression.
  • Fig. S6. Platelet adhesion and thrombus formation depend on GPIbα-thrombin interaction but not catalytically active thrombin.
  • Table S1. Hematological and clinical baseline characteristics are similar between treatment groups.
  • Legends for movies S1 to S5
