Tidsram |
|---|---|---|
|
Cumulative Incidence of Clinically Relevant Bleeding Events
Tidsram: From first Pradaxa Pellets exposure until its discontinuation plus 3 days of residual effect period, switch to other anticoagulation therapy, or planned observation time, whichever occurred first. Up to 373 days.
|
Cumulative incidence of clinically relevant bleeding events was reported as the number of participants with clinically relevant bleeding events, defined as the composite of major bleeding events (MBE) and clinically relevant non-major (CRNM) bleeding events, according to recommendations from international thrombosis and hemostasis committees. MBE were defined as: fatal bleeding; clinically overt bleeding associated with a decrease in hemoglobin of at least 2 grams/deciliter in a 24-hour period; critical site bleeding; bleeding that required an intervention via invasive procedure; and overt bleeding for which a reversal agent was administered. CRNM bleeding was defined as: overt bleeding for which a blood product was administered and did not meet the criteria for major bleeding; bleeding that resulted in a medical or procedural intervention not meeting major bleeding criteria, including a medication change; and bleeding that resulted in hospitalization or an increased level of care. |
From first Pradaxa Pellets exposure until its discontinuation plus 3 days of residual effect period, switch to other anticoagulation therapy, or planned observation time, whichever occurred first. Up to 373 days.

Occurrence of Recurrent Venous Thromboembolic Event (VTE)
Tidsram: From first Pradaxa Pellets exposure until its discontinuation plus 3 days of residual effect period, switch to other anticoagulation therapy, or planned observation time, whichever occurred first. Up to 373 days.
|
The occurrence of VTE is reported as the number of participants with recurrent VTE including both symptomatic and asymptomatic events.
Symptomatic recurrent VTE is defined as radiologically-confirmed new venous thrombotic or embolic burden at least 7 days post-diagnosis of the index VTE, accompanied by signs and/or symptoms attributable to the new thromboembolism.
Asymptomatic VTE was defined by new thrombotic/embolic burden as disclosed by comparison of end-of-treatment imaging versus baseline imaging of the vascular region involved by the index VTE.
|
From first Pradaxa Pellets exposure until its discontinuation plus 3 days of residual effect period, switch to other anticoagulation therapy, or planned observation time, whichever occurred first. Up to 373 days.

Mortality Related to Thrombotic or Thromboembolic Events
Tidsram: From first Pradaxa Pellets exposure until its discontinuation plus 3 days of residual effect period, switch to other anticoagulation therapy, or planned observation time, whichever occurred first. Up to 373 days.

Occurrence of All Bleeding Events
Tidsram: From first Pradaxa Pellets exposure until its discontinuation plus 3 days of residual effect period, switch to other anticoagulation therapy, or planned observation time, whichever occurred first. Up to 373 days.
|
The occurrence of all-bleeding events is reported as the number of participants experiencing any of the bleeding event described. All bleeding events were defined as the composite of major bleeding events (MBE), clinically relevant non-major (CRNM) bleeding events and minor bleeding events but not leading to hospitalization, increased level of inpatient care, or an intervention by the medical team. Minor bleeding events were defined as any overt or macroscopic evidence of bleeding that does not fulfil the criteria for major bleeding, CRNM bleeding, or important bleeding without intervention according to recommendations from international thrombosis and hemostasis committees. |
