Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
In total, 817 patients were enrolled from 3 countries (Japan, South Korea and Taiwan). Of the randomised patients, most patients were Japanese (723 [90.3%]). The first patient was enrolled on 28 February 2010 and the last patient completed the study on 31 July 2012.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
In total, 801 patients (401 in the ticagrelor [AZD6140 90 mg bd] group and 400 patients in the clopidogrel [clopidogrel 75 mg od] group) were randomised to treatment. The reasons for not being randomised were “Incorrect enrolment before randomisation” and “Patient decision (withdrawal of consent)”.

Reporting Groups
Ticagrelor (AZD6140) Ticagrelor (AZD6140) 90 mg bid
Clopidogrel Clopidogrel 75mg od

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
One discontinued patient (due to withdrawal of consent) in Ticagrelor (AZD6140) group did not agree to disclose any data. Thus the number of baseline participants in Ticagrelor (AZD6140) group is 400 instead of 401 that is the number of participants who started the first period.
