Event Rate of Composite of Adjudicated Major Bleeding and Clinically Relevant Non-Major Bleeding During the Treatment Period- Treated Participants With Placebo or Apixaban Low Doses
Bleeding was assessed using the International Society on Thrombosis and Hemostasis (ISTH) guidelines. Events were adjudicated by the Clinical Events Committee (CEC). Event rate was number of participants with events divided by the number of participants treated, measured as a percentage (%). The primary outcome is based on data for the placebo and 2 apixaban low-dose groups (2.5 mg BID and 10 mg QD) combined across Phase A and Phase B. The analyses of Phase B data across all doses of apixaban are secondary because of the premature termination of the apixaban high-dose groups (10mg BID, 20mg QD) and the resulting lower duration of exposure for these groups.
Time frame: From first dose of study drug (Day 1) to last dose plus 2 days, up to Year 2 of the Study
Number of Participants With a Composite of Adjudicated Cardiovascular Death, Non-Fatal Myocardial Infarction, Severe Recurrent Ischemia and Non-Hemorrhagic Stroke During the Intended Treatment Period - Randomized Participants
Events were adjudicated by the Clinical Events Committee (CEC). Intended Treatment Period refers to the period starting on the day of randomization and ending 182 days after the day of randomization (for a total period duration of 183 days). Data in this outcome are combined across Phase A and Phase B.
Time frame: Randomization to 182 days after randomization (183 days)
Event Rate for Adjudicated All Bleeding Events During the Treatment Period - Treated Participants With Placebo or Apixaban Low Doses
Bleeding was assessed using the International Society on Thrombosis and Hemostasis (ISTH) guidelines. Events were adjudicated by the Clinical Events Committee (CEC). Event rate was number of participants with events divided by the number of participants treated (%). All bleeding events includes major bleeding, clinically relevant non-major bleeding and minor bleeding. Treatment Period refers to the period from first dose through 2 days, or through 30 days for Serious Adverse Event (SAE) tabulations, after discontinuation of study drug. Data in this outcome are combined across Phase A and Phase B.

Number of Participants With a Composite of Adjudicated All-Cause Death, Non-Fatal Myocardial Infarction, Severe Recurrent Ischemia, and Non-Hemorrhagic Stroke During the Intended Treatment Period - Randomized Participants
Events were adjudicated by the Clinical Events Committee (CEC). Event rate was number of participants with events divided by the number of participants treated (%). Intended Treatment Period refers to the period starting on the day of randomization and ending 182 days after the day of randomization (for a total period duration of 183 days). Data in this outcome are combined across Phase A and Phase B
Time frame: Day of randomization to 182 days after day of randomization (183 days)
Event Rate of Confirmed Adjudicated Major Bleeding During the Treatment Period- Treated Participants With Placebo or Apixaban Low Doses
Bleeding was assessed using the ISTH guidelines. Events were adjudicated by the Clinical Events Committee. Event rate was number of participants with events divided by the number of participants treated, measured as a percentage (%).
Time frame: from first dose (Day 1) to last dose plus 2 days, up to Year 2 of the Study
Number of Participants With Composite of Adjudicated All-Cause Death, Non-Fatal Myocardial Infarction, Severe Recurrent Ischemia, Non-Hemorrhagic Stroke During the Phase B Adjusted Intended Treatment Period - Participants Randomized in Phase B
Phase B Adjusted Intended Treatment Period=day of randomization and ends on termination date of high dose apixaban, 1-Oct-2007. The analyses of Phase B data across all doses of apixaban are secondary due to the premature termination of the apixaban high dose groups and the lower duration of exposure.
Time frame: Day of randomization and ends on high dose termination date, 1-Oct-2007
Event Rate of Composite of Adjudicated Major Bleeding and Clinically Relevant Non-Major Bleeding During the Phase B Adjusted Treatment Period- Treated Participants Randomized in Phase B
Bleeding was assessed using ISTH guidelines. Events were adjudicated by the CEC. Event rate was number of participants with events divided by the number of participants treated, measured as a percentage (%). The analyses of Phase B data across all doses of apixaban are secondary because of the premature termination of the apixaban high-dose groups and the lower duration of exposure. Phase B Adjusted Treatment Period=safety events occurring in the period from first dose through 2 days (or through 30 days for SAE tabulations) after the earliest of last dose date or 1-Oct-2007 (termination date for the 10 mg BID group).
Time frame: From first dose (Day 1) to last dose, plus 2 days (plus 30 days for SAEs), up to high dose termination, 1 October 2007
Event Rate for Adjudicated All Bleeding Events During the Phase B Adjusted Treatment Period - Treated Participants Randomized in Phase B
Bleeding was assessed using the ISTH guidelines. Events were adjudicated by the CEC. Event rate was number of participants with events divided by the number of participants treated (%). All bleeding events included major bleeding, clinically relevant non-major bleeding and minor bleeding. Phase B Adjusted Treatment Period=safety events occurring in the period from first dose through 2 days (or through 30 days for SAE tabulations) after the earliest of last dose date or 1-Oct-2007 (termination date for the 10 mg BID group).

Phase B Adjusted Intended Treatment Period=day of randomization and ends on 1-Oct-2007. The analyses of Phase B data across all doses of apixaban are secondary due to the premature termination of the apixaban high dose groups and the lower duration of exposure.
Time frame: Day of randomization up to high dose termination, 1-Oct-2007
Event Rate of Confirmed Adjudicated Major Bleeding During the Phase B Adjusted Treatment Period - Treated Participants Randomized in Phase B
