VTE included any proximal or distal Deep Vein Thrombosis \[DVT\] (symptomatic or not) and non-fatal Pulmonary Embolism \[PE\] as confirmed by a Central Independent Adjudication Committee \[CIAC\] after central and blind review of mandatory bilateral venograms and diagnostic tests for VTE. All-cause deaths included fatal PE and deaths for other reason than PE.
VTE included any Deep Vein Thrombosis \[DVT\] (proximal or distal, symptomatic or not) and non-fatal Pulmonary Embolism \[PE\] as confirmed by a Central Independent Adjudication Committee \[CIAC\] after review of mandatory bilateral venograms and diagnostic tests for VTE. All-cause deaths included fatal PE and deaths for other reason than PE.
VTE included any symptomatic Deep Vein Thrombosis \[DVT\] of lower or upper limbs and any non-fatal Pulmonary Embolism \[PE\] as confirmed by a Central Independent Adjudication Committee \[CIAC\] after review of compression ultrasound or venography for DVT, ventilation/perfusion lung scan, pulmonary angiogram or spiral computer tomography lung scan for PE. VTE-related death included fatal PE and unexplained deaths without confirmatory autopsy. Any sudden death could be classified as fatal PE by the CIAC unless diagnostic test results strongly indicated an alternative diagnosis".
Participants alive and not having experienced VTE were right censored at last study drug injection plus 3 days. In order to correct for competing risks (Deaths other than VTE-related death), a model of cause-specific hazards was used to estimate the Cumulative incidence Function with Prentice non-parametric estimator.
VTE included any proximal or distal Deep Vein Thrombosis \[DVT\] (symptomatic or not) and non-fatal Pulmonary Embolism \[PE\] as confirmed by a Central Independent Adjudication Committee \[CIAC\] after review of mandatory bilateral venograms and diagnostic tests for VTE. All-cause deaths included fatal PE and deaths for other reason than PE.
VTE include any Deep Vein Thrombosis (DVT) (symptomatic or not) and non-fatal Pulmonary Embolism (PE) as confirmed by a Central Independent Adjudication Committee (CIAC) after review of mandatory bilateral venograms and diagnostic tests for suspected VTE. All-cause deaths include fatal PE and deaths for other reason than PE.
VTE includes any proximal or distal Deep Vein Thrombosis (DVT) (symptomatic or not) and non-fatal Pulmonary Embolism (PE) as confirmed by a Central Independent Adjudication Committee (CIAC) after review of mandatory bilateral venograms and diagnostic tests for VTE. All-cause deaths includes fatal PE and deaths for other reason than PE.
VTE included any Deep Vein Thrombosis \[DVT\] identified on mandatory venography of the lower limbs; symptomatic DVT and/or non-fatal pulmonary embolism \[PE\] before mandatory examination; VTE related deaths included fatal PE or deaths which could not be attributed to a documented cause and for which PE could not be ruled out. All events were to be confirmed by a Central Independent Adjudication Committee \[CIAC\] based on venographies, scheduled or unscheduled, and other available diagnostic tests (ultrasonography, ventilation/perfusion lung scan, pulmonary angiography, autopsy report, etc).
