Primary Outcome Measures:
  • Numbers of Patients With First Occurence of Stroke [ Time Frame: From start of treatment to end of follow-up period ( follow-up periods : 29 months [Standard Deviation 16, range 1-59 months]) ] [ Designated as safety issue: No ]
    The endpoint in this measure is a composite endpoint of the first recurrence of cerebral infarction, or occurrence of cerebral haemorrhage or subarachnoid haemorrhage. The evaluation committee, whose members were unaware of patients' treatment assignment, adjudicated all trial endpoints.


Secondary Outcome Measures:
  • Number of Patients With First Recurrence of Cerebral Infarction [ Time Frame: From start of treatment to end of follow-up period (mean follow-up periods : 29 months [STANDARD DEVIATION 16, range 1-59 months]) ] [ Designated as safety issue: No ]
  • Number of Patients With First Occurrence of Ischaemic Cerebrovascular Disease [ Time Frame: From start of treatment to end of follow-up period ( follow-up periods : 29 months [STANDARD DEVIATION 16, range 1-59 months]) ] [ Designated as safety issue: No ]
    The endpoint in this measure is a composite endpoint of the first recurrence of cerebral infarction or the first occurrence of transient ischaemic attack. The evaluation committee, whose members were unaware of patients' treatment assignment, adjudicated all trial endpoints.

  • Number of Deaths From Any Cause [ Time Frame: From start of treatment to end of follow-up period ( follow-up periods : 29 months [STANDARD DEVIATION 16, range 1-59 months]) ] [ Designated as safety issue: No ]
    Number of deaths from any cause. The evaluation committee, whose members were unaware of patients' treatment assignment, adjudicated all trial endpoints.

  • Number of Patients With First Occurrence of a Composite Endpoint of Stroke, Haemorrhagic Events, or Cardiovascular Events [ Time Frame: From start of treatment to end of follow-up period ( follow-up periods : 29 months [STANDARD DEVIATION 16, range 1-59 months]) ] [ Designated as safety issue: No ]
    The endpoint in this measure is a composite endpoint of the first recurrence of cerebral infarction, or occurrence of cerebral haemorrhage, subarachnoid haemorrhage, transient ischaemic attack, angina pectris, myocardial infarction, heart failure, or haemorrhage requiring hospital admission. The evaluation committee, whose members were unaware of patients' treatment assignment, adjudicated all trial endpoints.
