|---|---|---|---|
| Primary | Number of Participants With Recurrent Symptomatic Venous Thromboembolism (VTE) and Deaths Related to VTE | For statistical analysis 1: from randomisation to end of post treatment period (ptp), planned to be up to day 224. For statistical analysis 2: from randomisation to 6 months (up to day 180) | All suspected recurrent VTEs and all deaths and bleeding events were evaluated by an independent central adjudication committee, and all analyses are based on the events that were centrally confirmed by this committee. |
| Secondary | Number of Participants With Recurrent Symptomatic VTE and All Deaths | For statistical analysis 1: from randomisation to 6 months (up to day 180) For statistical analysis 2: from randomisation to end of ptp, planned to be up to day 224. | VTE or any death which occured from randomisation to end of post treatment period. All suspected recurrent VTEs and all deaths and bleeding events were evaluated by an independent central adjudication committee, and all analyses are based on the events that were centrally confirmed by this committee. |

Nuisance bleeding events were defined as all other bleeding events that did not fulfil the criteria from above. |
| Secondary | Number of Participants With Acute Coronary Syndrome (ACS) | From first intake of study drug to end of study conduct | Any ACS occurring during the conduct of the study (centrally adjudicated as definite). Counts of patients having a centrally adjudicated definite ACS during intake of active study drug, after stopping active study drug and before or without intake of active study drug, according to treatment group. All suspected recurrent VTEs and all deaths and bleeding events were evaluated by an independent central adjudication committee, and all analyses are based on the events that were centrally confirmed by this committee. |
| Secondary | Laboratory Analyses | From first intake of study drug to last intake of study drug + 6 days washout (washout time can be reduced until 0 day if the patient takes an other anti-coagulant therapy on and after last intake of active study drug) | Frequency of patients with possible clinically significant abnormalities. |
