Groups2
Group 2 names the comparator: usual care.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Apixaban | Participants with non-valvular atrial fibrillation undergoing cardioversion, received Apixaban orally for 30 days after cardioversion or 90 days after randomization if cardioversion was not performed. The dosing of Apixaban was based on investigator's judgement as per local label for the prevention of stroke and systemic embolism in participants. | 0 | 753 | OG000 |
| Group 2 | Parenteral Heparin/Oral Vitamin K Antagonist (Usual Care) | Participants with non-valvular atrial fibrillation undergoing cardioversion, received parenteral heparin and/or oral Vitamin K antagonist as usual care, orally for 30 days after cardioversion or 90 days after randomization if cardioversion was not performed. The dosing of the parenteral heparin and Vitamin K antagonist was based on individual participant's sensitivity to the drug according to the investigators usual practice. | 6 | 747 | OG001 |
