Prostocycline's Anti-Plated Effect

The threshold level of four nanograms per mil, this was based on prior data that you've already generated. The exclusion criteria for those not suitable for the study included life-threatening bleeding, but not other forms of bleeding such as traumatic brain injury. We have done five studies in total in critical ill patients with a low dose prostocycan. And we have not been able to measure any effect on the platelets or on bleeding complications. That isn't same as that there is no effect, but we just cannot measure it.
