Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Warfarin | Participants diagnosed with NVAF who initiated treatment with warfarin between 01-January-2013 to 30-June-2018 were observed in this retrospective study. Participants were followed up until July 2019. | 1 | 459 | EG000 |
| Group 2 | NOACs | Participants diagnosed with NVAF, who initiated treatment with any of the NOACs (dabigatran, rivaroxaban and apixaban) between 01-January-2013 and 30-June-2018 were observed in this retrospective study. Participants who were exposed to warfarin before 2013 and initiated NOACs between 01-January-2013 and 30-June-2018 were also included. Participants were followed up until July 2019. | 5 | 1,617 | EG001 |
