All events were adjudicated and confirmed by a central independent adjudication committee blinded to treatment. Events were assessed based on either compression ultrasound (for DVT), venography (for DVT), spiral computed tomography (CT) scanning (for PE), pulmonary angiography (for PE), ventilation/perfusion lung scan (for PE), lung scintigraphy (for PE), autopsy (for fatal PE) or unexplained death for which DVT/PE could not be ruled out (for fatal PE), and/or case summaries.

The intention-to-treat (ITT) population consisted of all randomized participants with valid informed consent. Participants were analyzed according to the treatment assigned at randomization.

Net clinical benefit 1: composite of recurrent DVT or non-fatal or fatal PE, and major bleeding. Major bleeding was overt bleeding associated with 2 g/dL or greater fall in hemoglobin, leading to a transfusion of ≥2 units, occurring in a critical site or contributing to death. Net clinical benefit was considered greater in those participants with fewer composite events. All events were adjudicated and confirmed by a central independent adjudication committee blinded to treatment, based on either compression ultrasound, venography, spiral computed tomography scanning, pulmonary angiography, ventilation/perfusion lung scan, lung scintigraphy, autopsy or unexplained death for which DVT/PE could not be ruled out, results/films/images of confirmatory testing, and/or case summaries.

All events were adjudicated and confirmed by a central independent adjudication committee blinded to treatment. Clinically relevant bleeding included major bleeding (overt bleeding associated with 2 g/dL or greater fall in hemoglobin, leading to a transfusion of 2 or more units of packed red blood cells or whole blood, occurring in a critical site or contributing to death) and non-major bleeding associated with medical intervention, unscheduled physician contact, (temporary) cessation of study treatment, discomfort for the participants such as pain, or impairment of activities of daily life.

The valid-for-safety analysis population consisted of all participants who were randomized with valid informed consent and received at least one dose of anticoagulant study treatment after randomization (i.e. enoxaparin, warfarin, acenocoumarol, rivaroxaban). Participants were analyzed according to the treatment they actually received.

All pre-defined vascular events (ST segment elevation myocardial infarction, non ST segment elevation myocardial infarction, unstable angina, ischemic stroke, transient ischemic attack, non-central nervous system systemic embolism or vascular death) were adjudicated and confirmed by a central independent adjudication committee blinded to treatment.

Participants entering the observational period were participants for whom the investigator indicated on the eCRF (electronic case report form) that the participant entered the observational period or had a confirmed event more than one day and up to 30 days after the last dose as a component of the respective composite outcome.
