Thus, the included bleeding types (spontaneous intracerebral haemorrhage, spontaneous subarachnoid haemorrhage, traumatic intracerebral haemorrhage or subarachnoid haemorrhage and traumatic subdural haemorrhage) will be studied separately as well as in relation to each OAC reversal group (reversal of dabigatran, FXa inhibitors and VKAs, respectively) (figure 1). The gene discussed is F10; the disease is intracerebral hemorrhage.
