Number of Participants With a Composite Endpoint of Stroke and Systemic Embolic Events (SEE) in Participants Who Were Administered DU-176b Compared With Placebo
Stroke was defined as an abrupt onset, over minutes to hours, of symptoms representing focal neurological deficit in the domain supplied by a single brain artery (including the retinal artery) and that was not due to an identifiable non-vascular cause (such as brain tumor or trauma). The deficit symptoms had to either last for more than 24 hours or result in death within 24 hours of symptom onset. A systemic embolic event (SEE) was defined as an abrupt episode of arterial insufficiency associated with clinical or radiologic evidence of arterial occlusion in the absence of other likely mechanisms (eg, atherosclerosis and instrumentation).
Time frame: Randomization up to the time of onset of the initial composite event of stroke or systemic embolic event, or study discontinuation, or end of study (whichever comes first), up to 3 years 2 months postdose (maximum follow-up time)
Number of Participants With Stroke and Systemic Embolic Events (SEE), Including Subcomponents of Stroke and Composite Event of Ischemic Stroke and SEE in Participants Who Were Administered DU-176b Compared With Placebo
Stroke was defined as an abrupt onset, over minutes to hours, of symptoms representing focal neurological deficit in the domain supplied by a single brain artery (including the retinal artery) and that was not due to an identifiable non-vascular cause (such as brain tumor or trauma). The deficit symptoms had to either last for more than 24 hours or result in death within 24 hours of symptom onset. Subcomponents of stroke (ischemic and hemorrhagic) were also reported. A systemic embolic event (SEE) was defined as an abrupt episode of arterial insufficiency associated with clinical or radiologic evidence of arterial occlusion in the absence of other likely mechanisms (eg, atherosclerosis and instrumentation).
Time frame: Randomization up to the time of onset of the initial composite event of stroke or systemic embolic event, or study discontinuation, or end of study (whichever comes first), up to 3 years 2 months postdose (maximum follow-up time)

Time frame: Randomization up to the time of onset of the initial composite event of stroke, systemic embolic event, or death due to CV, or study discontinuation, or end of study (whichever comes first), up to 3 years 2 months postdose (maximum follow-up time)
Number of Participants With a Composite Endpoint of a Major Adverse Cardiovascular Event (MACE) in Participants Who Were Administered DU-176b Compared With Placebo
Major adverse cardiovascular events (MACE) included a composite of non-fatal myocardial infarction (MI), non-fatal stroke, non-fatal systemic embolic events (SEE), and deaths due to cardiovascular (CV) or bleeding. Stroke was defined as an abrupt onset, over minutes to hours, of symptoms representing focal neurological deficit in the domain supplied by a single brain artery (including the retinal artery) and that was not due to an identifiable non-vascular cause (such as brain tumor or trauma). The deficit symptoms had to either last for more than 24 hours or result in death within 24 hours of symptom onset. A SEE was defined as an abrupt episode of arterial insufficiency associated with clinical or radiologic evidence of arterial occlusion in the absence of other likely mechanisms (eg, atherosclerosis and instrumentation).
Time frame: Randomization up to the time of onset of the initial MACE event, or study discontinuation, or end of study (whichever comes first), up to 3 years 2 months postdose (maximum follow-up time)
Number of Participants With a Composite Endpoint of Stroke, Systemic Embolic Events (SEE), and All-Cause Mortality in Participants Who Were Administered DU-176b Compared With Placebo
Stroke was defined as an abrupt onset, over minutes to hours, of symptoms representing focal neurological deficit in the domain supplied by a single brain artery (including the retinal artery) and that was not due to an identifiable non-vascular cause (such as brain tumor or trauma). The deficit symptoms had to either last for more than 24 hours or result in death within 24 hours of symptom onset. A systemic embolic event (SEE) was defined as an abrupt episode of arterial insufficiency associated with clinical or radiologic evidence of arterial occlusion in the absence of other likely mechanisms (eg, atherosclerosis and instrumentation). All-cause mortality was defined as death due to cardiovascular and mortality due to all other causes.
Time frame: Randomization up to the time of onset of the initial composite event of stroke, SEE, all-cause mortality, or study discontinuation, or end of study (whichever comes first), up to 3 years 2 months postdose (maximum follow-up time)
Number of Participants With Net Clinical Benefit in Participants Who Were Administered DU-176b Compared With Placebo
Net clinical benefit included a composite of stroke, systemic embolic events (SEE), major bleeding, and all-cause mortality. Stroke was defined as an abrupt onset of symptoms representing focal neurological deficit in the domain supplied by a single brain artery that was not due to an identifiable non-vascular cause. The deficit symptoms had to either last \>24 hours or result in death within 24 hours of symptom onset. A SEE was defined as an abrupt episode of arterial insufficiency associated with clinical or radiologic evidence of arterial occlusion in the absence of other likely mechanisms. Major bleeding was defined as overt bleeding that met at least 1 of the following criteria: fatal bleeding; retroperitoneal, intracranial, intraocular, intrathecal, intraarticular, or pericardial bleeding, or symptomatic intramuscular bleeding accompanied by compartment syndrome; or clinically overt bleeding that decreased hemoglobin by at least 2.0 g/dL and required blood transfusion.
Time frame: Randomization up to the time of onset of the initial composite event of stroke, SEE, major bleeding, all-cause mortality, or study discontinuation, or end of study (whichever comes first), up to 3 years 2 months postdose (maximum follow-up time)
Number of Participants With All-Cause Mortality in Participants Who Were Administered DU-176b Compared With Placebo
All-cause mortality was defined as death due to cardiovascular and mortality due to all other causes.
Time frame: Randomization up to death (due to any cause), or study discontinuation, or end of study (whichever comes first), up to 3 years 2 months postdose (maximum follow-up time)
Number of Participants With Major Bleeding During On-Treatment Period in Participants Who Were Administered DU-176b Compared With Placebo
Major bleeding was defined as overt bleeding that met at least 1 of the following criteria: fatal bleeding; retroperitoneal, intracranial, intraocular, intrathecal, intraarticular, or pericardial bleeding, or symptomatic intramuscular bleeding accompanied by compartment syndrome; or clinically overt bleeding that decreased hemoglobin by at least 2.0 g/dL and required blood transfusion.
Time frame: Baseline up to study discontinuation or end of study (whichever comes first), up to 3 years 2 months postdose (maximum follow-up time)
Number of Participants With Major Bleeding or Clinically Relevant Non-major Bleedings During On-Treatment Period in Participants Who Were Administered DU-176b Compared With Placebo
Major bleeding was defined as overt bleeding that met at least 1 of the following criteria: fatal bleeding; retroperitoneal, intracranial, intraocular, intrathecal, intraarticular, or pericardial bleeding, or symptomatic intramuscular bleeding accompanied by compartment syndrome; or clinically overt bleeding that decreased hemoglobin by at least 2.0 g/dL and required blood transfusion. Clinically overt bleeding that required treatment was taken to be clinically relevant non-major bleeding, including for example (but was not limited to) the bleeding that led to the diagnostic tests and treatments as specified in the protocol. The clinically overt bleeding requiring treatment did not include outpatient examinations that did not involve any of the medical procedures (diagnostic tests or treatments) as specified in the protocol.
Time frame: Baseline up to study discontinuation or end of study (whichever comes first), up to 3 years 2 months postdose (maximum follow-up time)
Number of Participants With All Bleeding Events and Minor Bleeding Events During On-Treatment Period in Participants Who Were Administered DU-176b Compared With Placebo
All bleeding events include major and clinically relevant non-major bleeding events. Other overt bleeding events that did not meet the criteria for major bleeding or clinically relevant non-major bleeding were taken to be minor bleeding (for example, epistaxis that did not require treatment). All events other than the above (such as a decrease in hemoglobin without overt bleeding) were classified as "non-bleeding event."
Time frame: Baseline up to study discontinuation or end of study (whichever comes first), up to 3 years 2 months postdose (maximum follow-up time)
